Kaishan Water-Cooled Screw Low Temperature Chiller

The water cooling mode and high-efficiency shell and tube heat exchanger save 18%-35% energy compared with equivalent air-cooled units. Stable condensation temperature ensures high efficiency under both full and partial load, greatly reducing long-term power cost of factories.

Compatible with industrial water and low-temperature ethylene glycol solution. The refrigeration range covers 0℃ to -40℃, meeting both regular cooling and deep low-temperature process requirements with one unit.

The semi-hermetic twin screw compressor is a mature industrial model. High-precision rotors achieve tight meshing and low internal leakage for stable power output. Optimized dynamic balance reduces vibration and noise below 78dB, complying with overseas factory environmental standards.

The industrial microcomputer collects real-time operating data with temperature accuracy up to ±0.1℃. 10%-100% stepless cooling capacity adjustment makes the unit change load automatically according to heat generation, avoiding frequent startup and shutdown and extending compressor life.

Shell and tube evaporator and condenser have large heat exchange area and fast heat conduction. The optimized flow channel prevents scale and impurity accumulation. Easy disassembly and cleaning reduce maintenance downtime.

Six major protection functions: high pressure, low pressure, compressor overload, water cut, freeze protection and phase sequence protection. The unit stops automatically and gives an alarm when faults occur, preventing equipment damage and production accidents, suitable for unattended operation.

The independent oil separator separates lubricant from refrigerant quickly. The recycled oil flows back to the compressor in a fully closed circuit without leakage. Sufficient and stable lubrication reduces oil replacement frequency and operating cost.

The thickened carbon steel cabinet with anti-corrosion plastic spraying is rust-proof, wear-resistant and anti-aging. IP54 dust-proof and splash-proof design enables long-term operation in dusty and humid workshops, and stable cooperation with outdoor cooling towers.

Custom services for explosion-proof, frequency conversion, remote monitoring, special refrigerant and non-standard voltage are available. We provide one-stop complete refrigeration systems including cooling towers, water pumps, water tanks, pipes and valves to meet overseas EPC project demands.
