Pool Cooling Unit (Pool Cooler)

Pool Cooling Chiller Unit

Product Features

The pool cooling chiller unit adopts a touch-type waterproof and dustproof control panel, with a cooling temperature range of 5–30°C. It uses Schneider, LG series, or Siemens contactors, and features a modular control system. It is equipped with multiple protection devices, including acid and alkali ingress protection, current overload protection, high and low pressure protection, and time delay protection. It provides timely fault alerts and displays the fault status.

This product uses a new refrigeration compressor, resulting in a higher energy efficiency ratio. The condenser is designed with a shell-and-tube structure, and the evaporator copper tubes use internally threaded copper tubes, which effectively improve heat exchange efficiency and facilitate cleaning.

The water pump is selected from Italian or Taiwanese high-flow, high-head pumps, ensuring safe, ultra-quiet, and energy-efficient operation. The unit's housing is finished with electrostatic powder coating, making it aesthetically pleasing. It is equipped with a stainless steel water tank for easy and quick cleaning. The tank includes a float ball automatic water replenishment device to measure and control water levels, effectively saving time and improving work efficiency for customers.

High-Temperature Pool Cooling Principle

Using the evaporative cooling method of the refrigeration compressor, the pump draws water from the high-temperature pool into the evaporator of the cooling unit, where it undergoes indirect heat exchange with the low-temperature refrigerant. The refrigeration process absorbs heat from the water in the high-temperature tank and expels it outside the unit. Through this cycle, the water in the tank is effectively cooled until the desired temperature is reached, at which point the unit automatically shuts down.

Main Application Industries

Pool cooling chiller units are mainly used for cooling industrial production equipment in industries such as plastic molding, injection molding, blow molding, casting, surface treatment, electroplating, electrophoretic deposition, electronics, circuit board production, electronic chip manufacturing, chemical industry, papermaking, pharmaceuticals, food processing, aluminum profiles, aluminum alloys, tempered glass, coated glass production, ultrasonic cleaning, jewelry processing, fur processing, and ink production.

Large Pool Cooling Chiller Unit

Semi-hermetic screw refrigeration compressors, with a 5:6 spiral rotor compressor, offer 20–30% higher energy efficiency than general compressors. They feature reliable operation, high efficiency, easy maintenance, capacity control, and a wide range of applications. Symmetrical rotor tooth profile, four-stage or stepless capacity control system, built-in differential pressure oil lubrication system, low vibration, and low noise.

Microcomputer-controlled temperature; the unit's microcomputer controller uses an LCD dot-matrix display with a full Chinese human-machine interface for fully automated control. The LCD screen displays real-time machine operation status and monitors the unit's running conditions. The sealed touch panel is waterproof, dustproof, corrosion-resistant, and has long button life. Staged and stepless energy control: for general air conditioning systems, there are 75%, 50%, and 25% staged energy control systems to ensure energy-saving effects under partial load. For precise water temperature control, all models can be equipped with stepless energy control as required by users. The heat exchanger uses corrugated tubes, combined with a screw compressor, ensuring reliable operation. Protective and auxiliary components include: compressor protection timer, overcurrent relay, compressor motor temperature sensor, anti-freeze thermostat, liquid sight glass, oil heater, compressor reverse phase protection relay, high and low pressure protection, exhaust high-temperature protection, and fusible plug. 

The refrigeration capacity ranges from 102,500 Kcal/h to 654,800 Kcal/h. In addition to the general features of water-cooled screw unit series, this series does not require a water cooling system and can be used in any well-ventilated area. Air-cooled units do not require auxiliary equipment such as cooling water pumps or cooling towers, significantly saving material and installation costs. They can even be used without a dedicated equipment room.

Small Pool Cooling Chiller Unit

The product line is comprehensive, including high-temperature (outlet water temperature 15°C), medium-temperature (outlet water temperature 5°C), and low-temperature (outlet water temperature -15°C) series. The structure is highly optimized, with a heat exchanger plate supporting the unit, making it simple, compact, and practical. The combination of a screw compressor and heat exchanger achieves an energy efficiency ratio of up to 4.5. Four-stage or stepless capacity control adapts to load changes. Compact size, high cooling capacity, reliable low-temperature performance. Designed for industrial applications, it includes a built-in low-temperature circulation water pump and stainless steel chilled water tank for extreme convenience. All materials in contact with water are corrosion-resistant, effectively preventing rust and corrosion. The microcomputer LED digital display controller features temperature display, temperature setting, automatic adjustment of chilled water temperature, and compressor delay protection. It uses branded contactors, relays, and other electrical components, with comprehensive indicator lights and switches for clear operation. The built-in electronic water level indicator and alarm device provide low-water-level automatic alerts, allowing operators to monitor the chilled water tank level via the control panel and replenish water promptly. Modular design ensures each compressor system operates independently; even if one system fails, it does not affect the others.
