Greenheck RV / RVE Rooftop Ventilator
The model RV(E) is a pre-engineered rooftop ventilation unit specifically designed to condition and deliver mixtures of outdoor and return air to a building. Varying outdoor air conditions and building loads create a serious challenge for any HVAC system. To overcome these challenges, the RV(E) includes value added features such as a factory mounted variable frequency drive (VFD) for supply air volume control, outdoor and return air dampers for mixed air control, and an onboard microprocessor system for precise temperature and humidity control. Pre-engineered features provide semi-custom flexibility while maintaining the quality, consistency, and value of a standardized product.
The RV(E) operates up to 18,000 cfm with an external static pressure of 3 inches. The unit can have indirect gas, hot water or electric heat as the heating options. The unit is also complete with packaged DX, chilled water or split DX cooling.
The model RV(E) has been specifically designed to meet the challenges of introducing high percentages of outdoor air into a building. Features included in the RV(E) minimize energy consumption, control outdoor air volume, and maintain high levels of indoor air quality. This makes the RV(E) ideal for ventilation applications in which the supply air volume consists of 20% or more outdoor air.
The model RV(E) comes as standard with double wall construction and has an option for a pre (MERV 8) and post (MERV 13) filter to meet the CSA Standard Z317.2, Special Requirements for HVAC Systems in Health Care Facilities.

Carrier 39M Aero Semi-Custom Central Station Air Handler
Carrier’s Aero 39M air handlers provide advanced technology and custom features in a streamlined, easy to install package. Indoor and outdoor units are available to handle a wide variety of applications. Units can be equipped with HEPA filters, stainless steel quad-sloped drain pans, AgION™ antimicrobial coating and other options. The 39M unit’s double-wall casing allows panels to be easily cleaned without damaging the insulation inside. Available fan options include forward-curved, airfoil, and plenum fans for extra quiet operation. Factory-installed controls maintain airflow and ventilation requirements while helping to prevent coil freeze-up, excessive humidity and poor indoor air quality (IAQ). Carrier’s AHUBuilder® software makes selecting and optimizing the 39M air handler easy.
The Carrier 39M units can come with hot water, steam and electric heat, chilled water and DX cooling, mixing boxes, various filtration options, humidifiers, air blenders, energy recovery ventilators, multiple fan options, face and bypass for the various heating and cooling coils. The units are a modular construction and can be broken down to fit into existing spaces to be re-assembled in sections once in place.
Carrier’s 39M now can come with indirect fired heating sections. The sections are available in the sizes 06-110 range and are from 100 to 6,000MBH with at least 3 heating input options per size. The standard turndown for the heaters is 10:1 with options available up to 60:1. Standard construction of the heat exchangers is 409 stainless steel with an option for type 304L stainless steel.
Another new feature for the units is the fan array direct drive plenum option. Dual fans are available from sizes 08 through 85. Four fan arrays in sizes 40 through 61. Six fan arrays in the largest size air handlers sizes 50 and larger. This provides additional redundancy for your air-handing needs.

Greenheck Vari-Green Motors and Controllers
The Vari-Green Motor is an electronically commutated (EC) motor that uses AC input power and internally converts it to a DC power supply which provides an 80% turndown capability and increased energy savings. The motors are offered in a direct drive configuration up to 2 hp. Motors, 1hp and smaller are available in 115VAC single phase power. Motors 1hp to 2hp are offered in either 115VAC or 208/230VAC single phase configurations.
Greenheck offers the Vari-Green motor on a number of fan models, including the centrifugal spun aluminum series (CUE, CW, G), inline series (SQ), propeller series (SE, SS) and the utility vent sets (SFD, SWD).
To further take advantage of the flexibility of the Vari-Green motor, Greenheck offers a number of built-in or remotely mounted controllers. Control offered by Greenheck are the remote speed control, fully adjustable two speed control, indoor air quality – temperature/humidity control and VOC control, as well as constant pressure (Static or velocity) controllers.
