Dectron’s Eco-Friendly Approach to Dehumidification

Businesses are becoming more and more insistent on leveraging technology that is both eco-friendly and cost effective. Dectron delivers on this growing demand with several industry-leading features that provide both an environmentally-friendly approach to dehumidification and an attractive return on investment.

A Focus on the Lowest Possible Refrigerant Charge

At the core of Dectron’s product philosophy is to have the lowest possible refrigerant charges across its line of dehumidification solutions. Traditional natatorium dehumidifiers require a large refrigerant charge that is not only expensive but also leads to oil and refrigerant migration control challenges that can impact compressor reliability.

Dectron’s Dry-O-Tron LEEDeR Series uses up to 85% less refrigerant charge compared to traditional DX systems. The Series also uses a water-glycol mix as a secondary heat exchange fluid to greatly reduce costs and environmental risks.

Refrigerant Pressure Transducers Eliminate Leaks

HVAC units that rely on manifold gauges are vulnerable to refrigerant loss whenever a service technician needs to remove these gauges to check the pressure of the refrigeration circuit.

Manifold gauge sets are responsible for the release of approximately 140,000 pounds of refrigerant around the world annually. This converts to nearly 300,000,000 pounds of CO2 every year.

Dectron’s equipment renders these issues obsolete. All units are factory-equipped with refrigerant pressure transducers, enabling service technicians to check the pressure of the refrigeration circuit from an Internet-connected device.

Dry Coolers: Premium Performance and Exceptional Efficiency

All Dectron units can be set up to reject heat outdoors to a dry cooler. These fluid-cooled systems are inherently environmentally friendly because of their low refrigerant charge.

Dectron’s Dry-O-Tron Dry Coolers are ideal for medium and large-scale fluid-cooled heat rejection needs and are available in capacities from 116 MBH to 2,300 MBH.
Modulating Reheat for Stable Room Conditions

Conventional compressorized dehumidifiers use a hot gas reheat coil with a simple on/off function, resulting in unstable space temperatures and RH level fluctuations. Compressorized Dectron units use a 0-100% modulating reheat coil to keep the space temperature and RH levels stable year round.

This modulating approach to reheat also results in less wear and tear on the compressor as the unit does not have to cycle between on/off modes and therefore constantly fill the coils with liquid refrigerant.

Direct-Drive Fans Reduce Operating Costs of the Entire Facility

Next to compressors, fans are the largest consumer of energy in an HVAC system, as they run 24 hours a day. Just reducing the operating costs of the fans significantly reduces the operating costs of the facility as a whole.

Direct-drive ECM and plenum fans with VFD offer the most efficient means of moving air while using the lowest possible fan energy. Antiquated belt-driven systems pose a maintenance concern and can consume as much as 25% more fan energy.

On a 32,000 CFM system, switching from a belt-driven DWDI blower to a direct-drive fan array could result in an annual operating cost savings of approximately $6,000 on fan energy alone (assuming 8,760 hours of runtime at a cost of $0.095/kWh). In just 15 years, cost savings could reach $90,000.

Direct-drive fans are standard across the entire Dectron product line. Not a single Dectron unit contains a belt-driven fan arrangement.
