The EcoFresh Energy / Enthalpy Recovery Wheel, which recovers total energy (sensible and latent), assists in meeting all the requirements of improving Indoor Air Quality (IAQ), humidity control and energy saving.
DRI is proudly the world's largest manufacturer of desiccant coated aluminium substrate Energy Recovery Wheels and has an installation history of 25+ years. It also has the largest installed base of such wheels all over the world in the most iconic buildings.
DRI offers the Highest Recovery Enthalpy Wheels in the world (Aluminium substrate coated with a choice of desiccants). These are incorporated into a Fresh Air Handing Unit or Energy Recovery Ventilator. In some cases, the wheel may be installed standalone with ducts.
Incorporation of EcoFresh Heat Wheels into the air-conditioning system means more outdoor air at lower energy cost (reduced loads).
Energy Recovery Wheels may also be known in the industry as Energy Conservation Wheels, Heat Wheels, Enthalpy Wheels, or Sorption Wheels. Sensible-only recovery Wheels are also referred to as Condensation Wheels. Hygroscopic recovery wheels have latent efficiency much lower than sorption wheel.
All DRI energy recovery wheels are certified. Eurovent certification and all AHRI program certification details are available on the website, in catalogues, and in writing to us.
We offer various diameters and depths of the rotors incorporated into cassettes. Rotors and Cassettes up-to a certain diameter are monolithic as a standard.
FlexAir Energy Recovery Ventilators provide a solution for Ventilation with Energy Recovery, to maintain good IAQ and Energy Savings in a single Unit.
Energy Recovery Ventilators are Plug-and-Play machines with an in-built starter panel and corded remote.
Energy Recovery Ventilators have a unique design and can be easily mounted in false ceilings. Incorporating the highest recovery Enthalpy Wheels, EcoFresh, these units are ideal for Homes, Banquet Halls, Gyms, Beauty Salons, Luxury Villas, Classrooms, etc.
We have hundreds of installations across many different applications. ERV is also ideal for the existing building where an easy plug-and-play solution is required to bring in the fresh air.
DRI Energy Recovery Ventilators are equipped with EcoFresh Energy Recovery Wheels capable of recovering sensible and latent energy from the stale exhaust air and transferring it to the fresh outside air. The rotating wheel transfers the sensible and latent energy between the counter-flowing exhaust and supply air, and in the process preconditions (cool/ heat/ dehumidify/ humidify) the fresh air.
Energy Recovery Ventilators (ERV) are also known in the industry as Heat Recovery Ventilators HRV, Energy Recovery Units ERU, and Heat Recovery Units, HRU.
The DRI ERV helps to meet ASHRAE 62 and other international standards specified ventilation rates without significantly increasing the air conditioning tonnage, saving capital, and operating costs considerably.
Ethylene removal is a natural process that does not affect the property of fruit or vegetable. Ethylene that is released naturally can be continuously removed by Bry-Air Ethylene Scrubber (BES) through the process of adsorption and chemisorption.
Bry-Air Ethylene Scrubber (BES) extends shelf life of fruits and vegetables, minimizes loss due to decay, ensures off season availability and eliminates harmful preservation practices that use Nitrogen and Sulphur gas. Fruits and vegetables, thus retain their naturalness and can be ripened as per demand without bearing traces of toxic gases.

GDT Series – Carbon Monoxide/Nitrogen Dioxide Detector
The GDT Series of gas monitoring sensors monitor levels of carbon monoxide (CO) and/or nitrogen dioxide (NO2) to provide an early warning of elevated concentrations.
The GDT is available as a standalone CO or NO2, as well as a CO/NO2 dual sensor device. The dual sensor device is available in 2 configurations: CO/NO2 housed one enclosure or as CO with remote NO2 sensor for mounting at a higher location.
The GDT gas sensors are encapsulated in field replaceable sensors pods that are located on the bottom of the enclosure. The pod design provides a greater area of gas sampling then that of devices that utilize a single vent hole. Replacement pods come pre-calibrated and ready for installation.
The GDT is available with either Analog, BACnet or Modbus outputs for communication with a building automation system. Standard features include LCD display for configuration and local display as well as status LED’s. Optional features include: 1 or 2 adjustable control/alarm relays, adjustable audible (buzzer) & visual (strobe) alarms as well as various temperature sensor.
The GDT is housed in an IP65 polycarbonate enclosure with a hinged and gasketed cover that provides ease of installation and access for set up and configuration.
Design Envelope technology is a demand based intelligent control solution that models equipment and system behavior, monitors actual system conditions, and dynamically adjusts equipment operation to match system demand. Design Envelope technology is at the core of Armstrong’s groundbreaking advances in building performance. Design Envelope technology enables the greenest, most flexible and most cost effective fluid-flow and HVAC systems on the planet – resulting in both, lowest installed and lowest operating cost with the same equipment
Generation 5 pumps, including Tango parallel pumps above, now meet the IE5 efficiency standard for motors. The new models can deliver up to 96.6% motor efficiency. This includes the new Design Envelope Tango parallel pumps and Design Envelope Vertical In-Line pumps up to 10 hp.
Design Envelope Permanent Magnet pumps that are engineered to deliver 20% lower operating costs than variable speed pumps with standard induction motors.
The new pumps are available with motors ranging from 15 hp to 50 hp, and operate at NEMA Ultra-Premium Efficiency levels that exceed the efficiency targets of both the US Department of Energy and the European Union.
Better performance at higher RPMs means that in some cases a smaller Design Envelope Permanent Magnet Pump can deliver the same flow and pressure as a larger, more expensive competing model,” said David Lee, Offering Manager, Armstrong Fluid Technology. “These new pumps also feature smaller dimensions and are less expensive to purchase and install because permanent magnet motors offer a substantial reduction in both size and weight.
Beyond the motor efficiency, a number of additional design innovations make the new Design Envelope pumps more energy-efficient and cost-effective:
Armstrong’s patented Parallel Sensorless Control stages multiple pumps and regulates output for best efficiency across the entire pump array, saving 10-30% in operating costs
Adjustable design points and setpoint based on the actual on-site conditions
A quadratic pressure control curve that provides more efficiency than a linear pressure control curve
A constant-flow function for maintaining a desired flow rate in recirculation applications
Advanced connectivity via Armstrong’s Pump Manager, a cloud-based performance tracking service, provides industry-leading analytics and insights along with alerts, alarms and data storage
