Product Introduction

GRAD Air-Cooled Screw Cold & Hot Water Unit | Air Cooled Screw Heat Pump Chiller

GRAD air-cooled screw cold (hot) water unit, also known as air cooled screw heat pump chiller, is a high-efficiency HVAC air-to-water system that takes ambient air as cold/heat source and water as heat transfer medium. This commercial & industrial screw air cooled chiller supports full cooling and heating functions for year-round continuous operation, featuring eco-friendly performance, outstanding energy efficiency, comfortable temperature control and ultra-stable running status.

Air-cooled screw chiller

Our GRAD air cooled screw unit integrates top-tier design, precision manufacturing and mature field application technologies. Equipped with core advantages including low-temperature stable operation, powerful heating capacity, multi-layer safety freeze protection, intelligent automatic defrosting system and full intelligent PLC control, this industrial air cooled screw chiller delivers superior operational reliability and an ultra-wide working temperature range. We provide diversified model specifications to match different project demands.

This air cooled screw heat pump unit is widely adopted in public commercial facilities: hotels, shopping malls, office buildings, exhibition halls, airports, stadiums and other central air conditioning projects. It also serves process cooling & heating requirements for multiple industrial sectors, covering electronics, pharmaceutical, biological, textile, chemical, metallurgy, electric power, machinery manufacturing and more industrial production lines. As a no-cooling-tower chiller, it greatly cuts installation and maintenance costs for global HVAC contractors and factory owners.

Working Principle

When the air-cooled water chiller is working, the refrigerant absorbs the heat from the cooled object in the evaporator and vaporizes. The compressor continuously draws the gas generated in the evaporator and compresses it into high-temperature and high-pressure vapor. The refrigerant vapor is then sent to the condenser to exchange heat with the air. After releasing heat, it condenses into liquid. The liquid refrigerant is decompressed after passing through the expansion valve. Then it enters the evaporator to absorb the heat of the cooled object and vaporizes again. This heat exchange process is repeated until the industrial water is cooled to the required temperature.

Application

Towerless air-cooled screw chillers for commercial & industrial cooling. Fit malls, hotels, data centers, food, chemical & electronics factories, great for water-shortage areas.
All-in-one air-cooled screw chiller units, easy outdoor rooftop installation. Reliable temperature control for HVAC and manufacturing process cooling worldwide.
