Product introduction
The air-cooled screw-type chilled (hot) water unit utilizes air as its cooling (heating) source and water as the refrigerant, capable of both cooling and heating operations year-round. It features environmental friendliness, energy efficiency, comfort, and stable performance.
GRAD's air-cooled screw chilled (hot) water unit incorporates advanced design, manufacturing, and application expertise. Equipped with core technologies such as low-temperature operation, high heating capacity, multiple antifreeze protections, intelligent defrosting, and smart control, the unit ensures high operational reliability and a broad working range. Available in diverse models, it is widely applied in public spaces like hotels, shopping malls, office buildings, exhibition halls, airports, and stadiums. Additionally, it meets the demands of various industries, including electronics, pharmaceuticals, biotechnology, textiles, chemicals, metallurgy, power generation, and machinery.
Operation range of air-cooled screw type cold (hot) water unit
● Large-diameter heat exchanger – Enhances low-temperature operation by reducing refrigerant flow resistance, increasing evaporation pressure, and inhibiting frost formation.
● Wide-spaced aluminum fins – Minimizes airflow resistance during low-temperature operation, boosting evaporation pressure and preventing frost buildup.
● Independent fin airflow control – Ensures precise regulation and more thorough defrosting.
● Integrated advanced technologies – Features a distributed defrosting system and piston-type four-way valve, eliminating common issues in traditional air-cooled heat pumps such as liquid suction, incomplete defrosting, and valve sticking.
