Overview

R410A Classical Modular Unit

The new generation environment-friendly modular air-to water heat pump is based on years of experience in R&D and design, which is greatly improved in aspects of the structure, system and microcomputer control technology, providing wider operation range of refrigeration and heating, and higher adaptability to applications with requirements on comfort and technology.
Perfect Combination for Small Tonnage Applications

Modular Air to Water Heat Pump Offers the perfect combination of flexibility, efficiency and low noise. Available in sizes ranging from 20 to 160 tons with a compact footprint. There are basic modules of any combination available for different models, and at most 16 modules can be connected in parallel.
Inherently More Efficient

Heat pumps use electricity to move energy up to a higher temperature to cool or heat the space. Because they move heat rather than generate heat, they can be three-times* more energy efficient than other forms of electric heating. In cooling mode, they move heat inside the building to outside. In heating mode, a reversing valve changes the flow of energy and moves outside energy (even if its cold outside) to inside the building.
Gain Reliable Year-Round Comfort

A perfect fit to meet your sustainability and efficiency targets. Enabled by our advanced controller, advanced adaptive control optimize performance. Post-installation, controller can connect with BMS energy analysis and 24/7 monitoring services to assure Withair® heat pumps are continuously optimized for efficiency and uptime.
