HEAT RECOVERY UNIT ( HRU )
Heat Recovery Unit (HRU) Supplier in India – Energy-Efficient HRU Ventilation Systems | Compress India
HRU stands for Heat Recovery Unit. In HVAC it is the ventilation unit that recovers thermal energy from the air a building is exhausting and transfers it into the incoming fresh air, so the primary cooling or heating plant has less outdoor air load to handle. The closely related ERV — Energy Recovery Ventilator — does the same job but recovers moisture as well as heat.
The distinction matters in specification. An HRU with a sensible-only core (plate or run-around coil) moves heat between the two air streams. An ERV uses an enthalpy wheel or membrane core and moves both heat and humidity, which is what most Indian projects need, because the latent load in the outdoor air is usually the larger half of the problem. Both are written as HRV, HRU or ERV on drawings and schedules for the same equipment.
We do not manufacture HRUs — we supply genuine, high-efficiency units suitable for modern HVAC installations.
What Is a Heat Recovery Unit (HRU)?
Understanding Heat Recovery Unit Systems
A Heat Recovery Unit (HRU) is an advanced ventilation device that transfers energy between exhaust air and fresh air streams. HRUs — commonly used in HRU ventilation systems — help reduce cooling and heating loads by recovering heat from outgoing air, improving overall energy efficiency and indoor comfort. These units work in conjunction with Air Handling Units (AHUs) and Fan Coil Units (FCUs) to create comprehensive, energy-efficient HVAC systems.
Types of HRU Systems We Supply
Counterflow Heat Recovery Units – High-efficiency units that ensure maximum heat transfer between exhaust and fresh air with superior thermal recovery.
Crossflow HRU Systems – Cost-effective heat recovery systems ideal for commercial ventilation projects and medium-scale applications.
Rotary Wheel HRU – Suitable for large buildings requiring continuous heat exchange with high-efficiency thermal recovery capabilities.

What is a Heat Recovery Unit ?
A heat recovery unit is an HVAC device that extracts heat from the exhaust air stream and uses it to preheat or precool the incoming outdoor air. This process reduces load on heating/cooling systems and significantly improves energy performance.
Usage HRU units are commonly employed in building ventilation systems to recover waste heat from exhaust air. By doing so, they reduce the need for extra heating or cooling, leading to lower energy costs and a smaller carbon footprint.
Energy Savings in Cold & Warm Climates
- In cold climates, HRUs preheat incoming fresh air using warm exhaust air, reducing boiler load and ensuring comfort.
- In warm climates, HRUs pre-cool intake air using outgoing cooler air, minimizing HVAC cooling demand.
