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 EBM brand fan is a three-phase fan with a very smooth and high performance with part number R3G400-AK53-05.

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.

TeSys GV2 can be used for a variety of applications in industry, infrastructure and buildings. It should be noted that the GV2LE22 circuit breaker has also been used in data center chillers. The GV2LE22 motor circuit breaker is a device that integrates the process of breaking the low voltage circuit and thermal overload relays. The device is able to protect motor branch circuits from overload, short circuit and phase loss. The working voltage of this circuit breaker is 690 VAC, and its rated current is 25 A. It is one of the important spare parts of Schneider coolers in data centers.

THERMAL OVERLOAD RELAY parts with part number LRD22 are overload relays for Schneider TeSys LRD range contactor.  The TeSys D range contactor is designed to make a motor starter. Such overload relays can be used with TeSys D contactors with a capacity of 9 to 38 amps. Such thermal differential overload relays detect excessive currents in motor lines. When excessive current is detected, the overload relay operates with the contactor to cuts off the power to the motor. This reduces damage to engine parts. The overload relay can set the trip current in the range of 16 to 24 amps.

Schneider TeSys LRD with part number LRD4367 is a thermal overcurrent protection relay used to protect 55 kW three-phase motors at 400 V. This relay has a differential device that detects load and phase imbalance. The product has a thermal adjustment dial, a manual-automatic reset switch that also functions as a reset button, a test button to simulate thermal overload, a stop button, a flag indicator and 2 auxiliary contacts 1NO + 1NC to indicate an error. It is used as spare part in the cooling equipment of data centers, including Schneider brand chillers and INROWS.

Flowmeter is one of the instrumentation sensors used to measure the volume or mass of fluids. We know flowmeters by other names such as flow indicator, mass meter and flow sensor. The Flowmeter MFS 20-200 l/min produced by Grundfos company is used in INRO ACRC301S coolers of data centers. The supply voltage of MFS 20-200 l/min is 5 VDC. The maximum pressure of the system can be 24 bar. It is one of the important spare parts of Schneider machines in data centers.
