Glycol Refrigeration
1. Wide range of operation,strong applicability
It can operate stably at-30℃~25℃ ambient temperature,and stably refrigerate at -30℃~48℃ ambient temperature.
2.High efficiency,energy saving,environmental protection and safety
High efficiency and energy saving, compared with the electric heating method,it can save 75%of electricity. Compared with traditional boiler equipment,no combustion,no exhaust gas emissions,no flammable and explosive safety risks.
3. Modular design,arbitrary combination,flexible application
● The unit adopts modular design,which can control up to 16 modules to meet the needs of different building loads;
● Convenient unit expansion,easy to stage investment.
An air source heat pump is an energy-efficient device that transfers heat from a low-temperature heat source (air) to a high-temperature heat source.
GRAD air source heat pumps/chillers are built on nearly two decades of engineering expertise, integrating advanced design, manufacturing, and application knowledge. Equipped with multiple core technologies—including low-temperature heating, multi-level antifreeze protection, intelligent defrosting, smart control, high operational reliability, a wide operating range, and diverse product options—these units deliver exceptional performance.
They are widely used in commercial and industrial settings such as hotels, shopping malls, office buildings, exhibition halls, airports, and stadiums. Additionally, they meet specialized air conditioning requirements in industries like electronics, pharmaceuticals, biotechnology, textiles, chemicals, metallurgy, power, and machinery.
Advantages
1.It operates efficiently within an ultra-wide ambient temperature range of -30℃ to 43℃
2. Precise frost measurement, rapid defrosting, reduced defrosting frequency, and shortened defrosting time
3. Mobile APP operation, remote control, fault warning, and online diagnosis
4. High-efficiency shell and tube heat exchange technology, water-side heat exchanger and flow protection, ultra-high energy efficiency ratio
5. It has a wide range of applications and is suitable for radiator heating, floor radiant heating, central air conditioning cooling and heating
