DC Inverter Air Cooled Chiller (Head Pump)

This DC inverter air cooled chiller with integrated head pump is an air-cooled industrial constant temperature cooling equipment adopting full DC variable frequency technology. Circulating pump is pre-installed inside the unit, eliminating the trouble of separately purchasing and matching external water pumps.

The complete MRC series ranges from MRC009EB to MRC040EB, covering mini small models to large industrial models. Equipped with DC inverter rotary/vortex compressor, DC variable speed axial fan and built-in circulating pump, matched with high-efficiency brazed plate heat exchanger.

The unit supports 15%-140% stepless cooling capacity adjustment, with ultra-wide ambient operating range and complete multiple safety protection functions. It is widely applied in industrial constant temperature cooling, precision processing, new energy, electronics, plastic and chemical industries.

Core Product Advantages

1. Full DC Inverter Design, Outstanding Energy Saving

   All core components including compressor, fan and circulating pump adopt DC variable frequency drive, maximum IPLV up to 4.31. Power consumption is reduced by 30%~40% compared with traditional fixed frequency chillers. The compressor operates in 15%-140% wide frequency range to accurately match real-time heat load.

2. Factory Built-in Head Pump, Simple Installation

   DC inverter pump or fixed frequency pump is optional pre-installed on the unit. All hydraulic components are assembled in factory, no extra pump purchase and complicated pipeline matching, saving installation space and construction cost. Multiple pump head options satisfy different pipeline pressure requirements.

3. Air-cooled Structure, No Cooling Tower Required

   Direct air heat exchange design without supporting cooling tower. The unit can be placed on terrace, roof or exterior wall, suitable for factories without space to install cooling towers. It simplifies pipeline layout and lowers later maintenance cost of water system.

4. Ultra-wide Operating Ambient Temperature

   Cooling working ambient temperature ranges from 10℃ to 48℃, stably outputting constant temperature cooling water of 5~30℃, adapting to high-temperature workshop environment.

5. Low Noise & Stable Operation

   Independent sound insulation compartment for compressor plus DC variable speed axial fan. Fan speed automatically adjusts following load, effectively cutting vibration and running noise, meeting low noise standard of laboratories and precision workshops.

6. Compact Body with Flexible Placement

   Integrated compact structure with multiple size specifications. Small models are light-weight for easy handling and installation; large models adopt reinforced frame for stable outdoor installation.

7. Comprehensive Multi-protection System

   Equipped with high/low pressure protection, overheat protection, overload protection, anti-freezing protection, phase loss protection, water flow protection, automatic fault alarm and data storage to guarantee long-term safe operation.

8. Eco-friendly R410A Refrigerant

   Adopts R410A refrigerant with low ozone depletion potential, featuring high heat exchange efficiency, low carbon emission and environmental friendliness.

Key Technical Parameters

Installation Instructions

1. Single Unit Standard Installation

   Place the unit on flat and solid ground, reserve sufficient ventilation space around air inlet and outlet to ensure normal heat dissipation.

2. Low Temperature Installation (Ambient Temp ＜5℃)

   When running cooling mode under ambient temperature below 5℃, air baffle must be mounted on air inlet side. Keep a clearance over 600mm between air baffle and the top & two sides of the unit to avoid poor heat exchange.

3. Water Pipeline Installation

   Adopt primary pump system or secondary pump system according to on-site cooling demands. Standard inlet/outlet pipe interfaces: Rc1 / Rc1 1/4 / R1 1/4. Max temperature difference between inlet and outlet water shall not exceed 7℃.

4. Maintenance Space Reservation

   Reserve maintenance space around the unit for filter cleaning, component replacement and regular overhaul.
