pCO5+ Programmable controller one response to the multiple current and future demands of the HVAC/R market.pCO5+ comes in 10 different sizes, guaranteeing an excellent solution for all HVAC/R applications.

EVD4 is an evolved PID controller complete with driver for stepper motors specially designed for the management of electronic expansion valves in refrigerant circuits. It features sophisticated control functions 

and can be used in many operating configurations in refrigeration and air-conditioning systems, such as:

- PID control of superheat with protection and safety compensation functions;

- PID control on one measurement (pressure or temperature);

- positioner for electronic expansion valves controlled by 4 to 20 mA or 0 to 10 Volt signal. 

The device is configured and the address set via serial interface and the user interface software is stored in non-volatile memory.

This electric current is measured by a current transformer: by varying the level of water using a fill solenoid valve and due to the evaporation process, the current, and consequently steam production, can be modulated. Due to evaporation, the level of water decreases and must therefore be topped up. As the steam produced does not carry mineral salts, the salt concentration in the water and therefore the conductivity increases, and has to be periodically diluted by draining part of it using the drain pump and replacing it with new water.

The CAREL DPW* series serial probes are devices used for applications in the air-conditioning, refrigeration, heating and air handling sectors. These are installed in combination with the controllers that feature the serial connection. As well as the wall-mounted room probes, industrial and duct versions are also available.

The German STEGO heater has a heater with a small body and an internal fan, with part number CSL028. Using a PTC heating element, it prevents the formation of moisture inside electrical and control cabinets with high component density. Its touch-safe plastic case ensures the safety of users by providing heat protection. This product is widely used in instrument control boards, electronic and electrical equipment and systems, as well as data center cooling system boards. It is one of the widely used spare parts of Schneider brand datacenter cooling systems, including chillers.

The continuous and accurate measurement of temperature and humidity is very important due to the high sensitivity of data centers environment to temperature and humidity. Therefore, with very accurate measuring devices, the necessary signals are always given to the system for the required controls. The W0N-0865 humidity sensor is used in the Schneider brand INROW ACRC602P cooler. It can be installed on a special base. This sensor converts the humidity of the environment into an electrical signal. It provides control circuits to adjust the humidity of the environment by activating or deactivating the fans. The cable length of the sensor is about 2.5 meters.

W0W2818 is a thermometer based on NTC thermal resistance, which is used to measure the ambient temperature of various INROWs, including Schneider INROW ACRC301S and Schneider INROW ACRC602P. This operational component converts temperature changes into current changes that can be understood by electronic circuits. Since it has a length of 4 meters, it can be installed at a relatively reasonable distance from the electronic circuit to measure heat. W0W2818 thermistor can measure the temperature between -55 to +125. It is one of the important spare parts of Schneider machines in data centers.

W0W1314 is a thermometer based on NTC thermal resistance, which is used to measure the ambient temperature of various INROWs, including Schneider INROWACRC301S and INROWACRC602P.
