Fighting condensation in enclosures.

The CS 032 enclosure heater from STEGO with fan delivers high performance and efficiency in a compact design, making it easy to install even in confined spaces. It is available as a Basic version with fixed heating power or as a Plus version with intelligent variable output control.

Electrical systems, particularly those housed in enclosures, often face harsh environmental conditions. This is especially true in power supply systems, renewable energy applications such as wind turbines, infrastructure projects, and mechanical engineering. These enclosures are frequently exposed to significant temperature fluctuations and high humidity levels, leading to the risk of condensation buildup.

Condensation can cause short circuits, which at best result in system shutdowns but, in the worst case, can damage or destroy electrical and electronic components. A proven solution to prevent this is the use of enclosure heaters.

With the CS 032 enclosure heater, STEGO Elektrotechnik introduces two compact models – CS 032 Basic and CS 032 Plus – both featuring integrated fans that combine efficiency and performance with flexible placement and easy installation.

With dimensions of 66 mm (width), 96 mm (height), and 120 mm (depth), these heaters fit even in densely packed enclosures. Designed for operating temperatures from -45°C to 70°C (-49°F to 158°F) and relative humidity levels of up to 90%, they offer a wide range of application possibilities. The units are available for 220-240 V AC and 110-120 V AC power supplies, ensuring compatibility across various electrical systems.

CS 032 Basic: Compact with Three Heating Power Options.
The Basic version is available in three models with fixed heating capacities of 600, 800, and 1,000 W. It can be easily integrated into an existing control system.

This enclosure heater offers flexible mounting options, allowing the warm airflow to be directed either sideways or vertically. Like the Plus version, it features an integrated automatic temperature monitor, which activates overheating protection in the unlikely event of a fan failure.

CS 032 Plus: More Flexibility with Enhanced Efficiency.
The Plus version features variable heating output ranging from 600 to 1,200 W and intelligent control for optimized heating operation. The desired temperature can be continuously adjusted using a control dial.

In cases of significant temperature drops (e.g., in extremely cold environments), the quick heating function activates, operating at maximum heating power and fan speed. When only minor deviations from the target temperature occur, the heater switches to an energy-saving mode with reduced output, adjusting over time. This optimizes energy consumption, reducing power usage by up to 23%.

The CS 032 Plus also offers greater flexibility in installation — it can even be mounted upside down. Another key benefit is the simplified inventory and preparation process, as only one unit is needed for various performance requirements.

Easy Installation and Safe Operation.
Space inside an enclosure is often limited, making installation challenging. To simplify this, the CS 032 comes with both a clip-mounting kit for 35 mm DIN rails and a screw-mounting option.

The push-in terminal allows for quick and tool-free electrical connection, reducing installation time by up to two-thirds while ensuring a stable and secure connection — even during transport of pre-configured enclosures.

When working inside an enclosure, safety is a top priority, particularly protection against accidental contact. The touch-safe plastic housing of the CS 032 enclosure heater ensures that it remains at a safe temperature, preventing any risk of injury during maintenance.

Early Warning of Condensation Danger.

The compact EE046 from E+E Elektronik monitors reliably the condensation danger on chilled beams and other critical cold spots, in air conditioning systems or switching cabinets. It can be installed on plane surfaces and on pipes up to 50 mm (2”) diameter. For preventing condensation, the switch output can trigger actuators like valves or heaters.

The EE046 measures accurately the relative humidity at the surface temperature. Thanks to the special E+E proprietary coating, the humidity sensor is optimally protected against contamination. This improves the lifetime and long-term stability of the EE046 in dirty, dusty environments. Another advantage of the condensation monitor is the fast response time to humidity or surface temperature change.

The potential-free relay (max. 24 V AC/DC, 1 A) switches when the relative humidity at the surface reaches 90% RH, or in case of a supply failure such as a broken cable. A LED indicates the status of the EE046: normal operation, risk of condensation or fault/failure.

Due to the compact design, the condensation monitor requires little space and the installation is remarkably simple. On plane surfaces, the EE046 is fixed with two screws, for mounting on pipes up to 50 mm in diameter a mounting strap is included in the scope of supply.

Optimising steam generation & condensate recovery processes for maximum profit.

Steam production can represent 10-60% of a plant’s total energy consumption depending on the industry. As a result, the steam generation cycle and supporting processes represent critical areas of opportunity for cost and performance benefits. Magnetrol International has developed the Steam Generation Cycle and Condensate Recovery Process Optimization Kit to help commercial and heavy industries identify the hidden costs that result from instrumentation poorly suited to their application in these processes. The Optimization Kit includes a white paper, video and applications guide to provide a comprehensive analysis of how a level and flow instrument’s fundamental technology, when properly matched to its application, can: Reduce fuel & energy consumption,  Improve steam quality,  Recover valuable energy & resources,  Ensure product quality,  Lower maintenance costs,  and Prevent production downtime. “Although plausible, it is rare to identify a single source of inefficiency related to poor level controls that impacts a company’s bottom line in the double digit percentile. More so than not, it is small incremental opportunities for improvement across various aspects of the steam generation cycle, condensate recovery and waste heat recovery processes that ultimately equate to substantial savings,” said Donald Hite, business development manager for Magnetrol. “Addressing these issues is analogous to stopping the seemingly innocuous, slow drip in a water faucet that over time consumes vast resources.” The Optimization Kit offers insight into the significance of maintaining proper level control and protective measures to realize potential savings in steam generation, waste heat and condensate recovery, and water treatment systems common in process industries such as power generation, pulp and paper, chemical, petroleum refining, primary metals and food processing. • Magnetrol products marketed in Ireland through Ntron @MagnetrolGlobal #PAuto

Condensate monitor.

Mountable on pipes and flat surfaces

The condensation monitor is an electronic Hygrostat, from B+B Sensors,  which is designed to sense dew formation or beginning of water condensation on cooled objects. As soon as the measured value of surface humidity exceeds a certain limit (approx. 94 % RH), it opens the relay contact and trips the static switch contact (safety function). For example, this signal can be used for switching on a heater.

With the new measurement philosophy and application of a special sensor with logarithmic characteristics, it is now possible to regulate very close to the dew start point. With the help of this technology, now the maximum cooling performance of the ceilings can be achieved, without the risk of condensate formation.

During product development, reliable mode of operation was the most important criterion. The circuit is protected against overvoltage, reverse polarity and faulty connections. In addition to the humidity sensing element, which reacts to the critical air humidity values below the condensation limit, there is a safety circuit which detects the dew occurence and independently trips the static power circuit. With the optimised AC-circuit technology, the sensor experiences even a short time contact with water without getting destroyed due to electrolysis effect.

A sinter filter over the sensor element protects it from accumulated dust and ensures many years of operation without cleaning or maintenance.

The condensation monitor is available in two different variants:

The model with attached tubular sensor can be directly mounted on the inlet of the cooling panels with minimum fitment expenses. The sensor with aluminium profile is fitted on the tube and fixed with the enclosed assembly strap. The wiring expenses are also very less. The device isprovided with a mains Iead and plug, which is only to be connected.

Spoiling your winter performance?

One of the problems encountered with outdoor enclosures is the onset of cold weather and consequently the possibility of condensation within the structure. In order to eliminate this unwanted natural event, Rittal’s standard range of heaters for their outdoor cabinet can keep the chill off delicate electronics housed within.

Coupled with effective designs incorporating a double wall design, Rittal’s heaters can ensure the installed equipment works faultlessly throughout periods of miserable weather. With 10 W and 800 W outputs the heaters may be positioned anywhere inside the enclosures to prevent temperatures dropping below operational levels.

Avoid forming of irritating droplets and wetness

Cooling ceilings, critical areas in HVAC and technical installations, which are operating close to the dewpoint temperature, need an early alarm system against the forming of moisture, because of the potential danger of condensation. The new condensation monitor EE46 from E+E Elektronik is specially designed for such applications and can be installed in a few seconds on pipelines, walls, and ceilings.

The early detection of “danger of condensation” and as a result the immediate start of counter measures renders this product as very significant.

A special coating protects the sensor and electronics against dirt and dust – a guarantee for a longstanding, stable and above all maintenance free operation.

The fast response, high accurate E+E humidity sensor is exposed to the temperature of the surface of the object by means of a thermal conducting foil. Therefore, the humidity sensor measures the same relative humidity as is present at the surface of the object to be monitored.

If the preset set point of 90 %RH is exceeded the EE46 switches a potential free contact and provides a signal enabling to take early counter measures, e.g. to increase the temperature of the water in the pipe, to decrease the cooling power or to turn on the heat. In addition, a LED on the enclosure indicates the actual status.

The condensation monitor of the Series EE46 is designed to be powered by 24 V ac/dc.
