Thermal Care Accuchiller 23 Ton NQW20 Water-Cooled Portable Chiller
NQ Series portable chillers use components such as R410A refrigerant, scroll compressors, micro-channel condensers, low noise fans, stainless steel brazed plate evaporators, and sophisticated controls provide the best available technologies for the ultimate performance and reliability in a chiller package.
Chillers usually operate with process heat loads less than 100% of available chiller capacity. With increasing emphasis on energy efficiency, we offer a variable-speed scroll compressor for improved part-load efficiency. Most chillers use fixed-speed compressors with a hot gas bypass valve that bypasses hot discharge refrigerant gas back into the compressor to simulate 100% load. This keeps the compressor running at full speed all the time. Our variable-speed scroll compressor technology varies the compressor speed to match the process load. This means the compressor slows down under part load conditions for peak performance and reduced power use. Our 5, 10, and 15 ton units use one variable-speed compressor. Our 20 ton unit uses a 10 ton variable-speed and a 10 ton fixed-speed compressor and our 30 ton unit uses a 15 ton variable-speed and 15 ton fixed-speed compressor.
Direct Drive Scroll Compressors
Direct drive hermetically sealed scroll compressors with
proven performance in industrial cooling for reliable, low
maintenance, and efficient operation.
Stainless Steel Evaporators:
High-efficiency stainless steel plates with copper brazing
provide maximum performance, long life, and an enhanced
level of protection from harsh process conditions.
Stainless Steel Pump:
Stainless steel pump selected for peak performance with
the utmost in corrosion protection to ensure a long useful
life under severe industrial conditions.
Nonferrous Reservoir and Water Lines:
The insulated reservoir, fluid lines, pumps, and other
components in the process fluid circuit will remain free of
rust to provide maximum corrosion protection.
Evaporator Inlet Strainer:
The evaporator inlet strainer removes any debris present in
the process fluid to prevent costly downtime and repair
due to a clogged chiller evaporator.
Easy Access Cabinet:
Heavy-gauge machine access doors with industrial grade
tools-free latches provide quick access to all components
for easy operation and maintenance.
Compressor Protection Technology:
Our compressor protection technology uses start-to-start
anti-recycle control logic to limit cycling under low-load
operating conditions to extend compressor life.
Compressor and Pump Run Hour Displays:
The ability to monitor compressor and pump running
hours is useful and is an important tool to assist with
The main power monitoring system protects the chiller
from extensive damage to the compressor and pump due
to loss of phase or phase reversal in the main supply.
Reservoir Low Level Alarm:
Indicates a low process fluid condition and protects the
process pump and chiller from expensive damage caused
by a critically low operating level in the reservoir.
The master reset function is a quick and easy way to reset
and restore the control system to factory default settings if
a control parameter is mistakenly changed.
High-Quality 24 VDC Power Supply:
The 24-volt DC power supply ensures dependable control
circuit power and isolates the control circuit from static
interference to ensure stable and precise operation.
