Composition
The NetCol5000-A020 consists of a cabinet, a compressor, EC fans, an evaporator, air filters,
expansion valves, a surge protection and filtering board, an electric heater (optional), and an
electrode humidifier (optional).
Compressor
The high-efficiency scroll compressor is used, which features good environment
adaptability, high reliability, low noise, long service life, and easy installation. The
R410A refrigerant is environmentally friendly.
EC fan
The brand fans are used, featuring less power consumption, high efficiency, high power
coefficient, optimal speed adjustment, and simple control. Compared with common fans,
such fans are highly reliable with redundancy design and save 30% more energy.
Evaporator
The highly efficient finned-pipe evaporator with threaded copper pipes and a zinc-plated
layer adopts the computational fluid dynamics (CFD) to optimize the process design,
which greatly improves the heat exchange efficiency.
Air filter
G3 air filters are used, meeting requirements for equipment room cleanness.
Expansion valve
The external equalizer type thermostatic expansion valve automatically balances the
refrigerant flow, ensuring efficient heat exchange and system reliability.
