Advanced Modular Air-Cooled Chiller System for Printing Solutions

Product Description

Product Description

The SJ series modular air-cooled chiller and heat pump unit integrates the essence of air-source heat pump design and is tailored to meet the practical demands of the Chinese modular unit market. It is engineered to maximize efficiency, safety, intelligence, and comfort, fully addressing the needs of modern users.

With high energy efficiency and multi-functionality (cooling, heating, and domestic hot water), the unit operates reliably even in ultra-low temperatures. It is ideal for villas, hotels, resorts, entertainment venues, hospitals, restaurants, office buildings, supermarkets, and other facilities requiring both air conditioning and hot water.

By utilizing waste heat for water heating, it not only reduces the operational cost of the HVAC system but also provides "free" hot water. Additionally, this series is also suitable for various industrial cooling applications.

Note:
1.The testing condition of nominal cooling:
Outlet water temp. is 7*C. Water flow rate is 0.172m*/(h-kW). Outdoor ambient temp. is 35°C

2.The testing condition of nominal heating:
Outlet water temp. is 45°c. Water flow rate is 0.172m3/(h:kw). Outdoor ambient dry/wet bulb temp. are 7 °C/6°C

3.Chiller water resistance includes water pressure drop of unit and the accompanyingY-type filter's.,

4.The main water pipe of the combined units needs to be installed on site, and the pipe diameter must meet the design standards
5.The modular chillers can be combined with the same or different modular units according to the needs.

6. The number of combined units are 1~16 sets,The above table is the common module chiler parameters
7.The power distribution and wiring in the site should follow the chiller's nameplate or installation instructions

Our advantages

1.Eco-friendly and superior performance

The unit uses high-efficiency, eco-friendly refrigerant R410A:

a. R410A refrigerant causes no damage to the ozone layer, making it a safer and more sustainable choice for the environment.

b. It offers excellent heat exchange performance, resulting in higher overall system efficiency.

c. Requires less refrigerant charge, which helps reduce the impact on global warming.

2.High efficiency and energy saving, effectively reducing operating costs

The unit adopts high-efficiency scroll compressors and heat exchangers, with an optimally matched system to achieve superior heat exchange performance.

It uses eco-friendly, high-efficiency R410A refrigerant to further enhance energy efficiency.

The multi-compressor, multi-circuit design allows for staged capacity control, reducing start-up current and minimizing electrical infrastructure investment.

 With a higher energy efficiency ratio (EER), the system delivers greater energy savings and effectively reduces actual operating costs.

3.Easy installation and convenient maintenance

On-site installation is simple—just connect each module's water pipes to the main system piping and hook up the power supply, and the unit is ready to operate.

Specially designed maintenance panels are reserved on the unit, allowing for easy disassembly and direct access to any internal components for convenient servicing.
