Energy Recover Ventilators (ERVs)


　EcoFresh ERVs help designers, engineers, consultants, building owners meet Indoor Air Quality (IAQ) standard and save energy.


　　The Ecofresh ERV exchanges stale, contaminated room air with fresh outdoor air, in the process also recovering upto 80% of the energy from the exhaust air. The energy recovered is used to precondition [precool/preheat] the supply air, thereby reducing the energy needed to condition fresh air.

　　This makes it possible to bring in more conditioned fresh air at lower cost. Installing the Ecofresh ERV thus helps to reduce capital/operating cost of airconditioning equipment in new as well as existing buildings. The energy recovery is achieved when the enthalph/energy recovery rotor slowly rotates between the counter flowing exhaust and supply air streams absorbing the sensible as well as the latent engergy from the cooler air stream and transferring it to the warmer air stream.

FEATURES OF ECOFRESH:

Selectivity: EcoFresh rotors, the heart of th e Ecofresh ERV, has a special grade low pore size zeolite desiccant of proprietary mix the "Ecosorb", Ecosorb eliminates carryover of bacteria and airborne contaminants, i.e. selective adsorption. Ecosorb allows only water molecules to pass through it and rejecting all other pollutants. Thus, the contaminants remain in the exhaust.
High Diffusion Rate: Ecosorb has the perfect combination of high selectivity and high diffusivity.
	Structural rigidity: Vertical and Radial run out less than 1mm upto 1000mm diameter.
Equal Sensible/Latent Effectiveness: Controlled desiccant coating, thickness and high moisture diffusion rates ensure equal sensible and latent energies resulting in a wide performance range.
Innovative Manufacturing Design: Innumerable Options, Bottom Opening [BO], Side Opening [SO] and all side opening possible[AO]

Benefits of Ecofresh ERVs:
Helps to meet IAQ standards
Improves indoor humidity levels
Reduces energy costs.
Lowers first as well as operating costs for air conditioning (due to reduced outdoor air load)
Designed to meet market needs for low maintenance and economical first cost.
Retrofitted easily into existing systems
