Product Overview

3HP low stage thermal conductive oil/ethanol/electronic liquids cooling system with 2-compressor

It select R410a as high temperature stage and R23 as low temperature stage. Some refrigerants are well suited for high and medium temperature applications, and some are better suited and for a lower temperature applications. In a cascade system the high/medium temp refrigerant circuit is used to cool the condenser of the low temperature circuit by the intercooler. In essence, the condenser for the low temperature system is also the evaporator or part of the evaporator of the high/medium temperature system.
The BOWA SOLUTION standard application solutions for chillers/heat pumps with screw, scroll & BLDC compressors are designed for various liquid temperature control. The application solution can manage both air/water and water/water units. The maximum configuration involves six compressors in each circuit, with up to two circuits. The built-in serial ports on the PCB board moreover allow information to be exchanged with the unit actuators (electronic valves, fan controllers, compressor inverter, etc.), thus optimising unit control and efficiency according to system requirements. Complete management of the compressor envelope allows the device to in safe conditions at all times, thus guaranteeing the highest performance. Indeed, whenever the compressor working approaches one of the operating limits defined by the envelope, specific prevention actions are adopted, involving varying compressor capacity (for BLDC compressors), condenser fan speed of condensation (on air/water units) and the opening of the electronic valve. The protection function is available for both BLDC compressors and ON/OFF scroll compressors.

FAQ
Q1:What informaiton does the buyer should provide when ordering
A1 : firstly, we need know what room temperature it requires. For example, we need -65'C cold room for super frozen tuna. Then we will get know evaporating we should design.
A2: We also need know (1) what product (2) How much weight (3) from which temperature to which temperature (4) within how much time.
A3: If air cooled, it need give ambient max. and min. temperature
