Dectron

Dubbing it HVAC industry’s most energy-efficient make-up air dehumidifier system for commercial, institutional and industrial applications, Dectron, manufacturer of indoor air quality and energy recovery equipment, has announced introducing Dry-O-Tron DK/RK Series heat recovery dehumidifiers.

The manufacturer claims that DK (indoor) RK (rooftop) Series offers the largest selection of standard and optional features aimed at reducing energy costs of outdoor air compliances of ASHRAE Standard-62 indoor air quality (IAQ) standards, and includes features such as, gas-phase air purification, electronically commutated (EC) motors, energy recovery method options and digital scroll compressor technology, when specifying a custom-manufactured make-up air system.

According to Dectron, ASHRAE Standard 62’s new IAQ Procedure (IAQP) option allows a reduction of outdoor air when gaseous air-cleaning devices are incorporated, such as, the RK/DK Series gas-phase air purification module supplied in-house by Dectron’s Circul-Aire subsidiary, and offers both relative humidity and temperature set point precision. The manufacturer claims that, in addition, the product employs variable hot gas reheat, electronic hot gas bypass, variable heat (for heat pump options) and digital scroll compressor technologies. Additional precision is ensured by onsite or remote monitoring and/or controlling with Dectron’s proprietary 16-bit microprocessor, the Supervisaire, which is compatible with all building automation system protocols, the manufacturer adds.

Dectron lists other product features and benefits:

• A 60-point quality control inspection under full load and design conditions in an advanced in-house test lab
• Rooftop model amenities of two-inch foam insulation, four-coat paint process, hinged access doors with vinyl compression gaskets and cam latches and stainless steel hardware
• A choice of three environmentally friendly refrigerants – R-134a, R-407C or R-410A
• Blower/motor assemblies combined with digital scroll compressors ensure a quiet operating unit
• Exhaust energy recovery also offers a variety of methods, including enthalpy wheels, heat pipes, and plate-type technologies to reduce heating and cooling energy requirements
• Direct drive plenum or plug fans with a choice of either variable frequency drives or EC motors increase efficiencies up to 14% more versus conventional motors and belt drives
