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 9,500 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.

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.

Price Critical Controls

Price Critical Controls

Price Industries has expanded the controls products. There are now two primary groups, HVAC System Controls and Critical Controls.

Healthcare facilities have long used pressure differentials between rooms as a method of protecting patients and staff from potential airborne contaminants and infectious pathogens. Price offers high-performance Critical Control solutions for operating rooms, patient rooms and isolation rooms.

The Price Room Pressure Monitor (PMX) is designed to provide intelligent room pressure monitoring of critical environments.

The PMX measures the differential room pressure through a Room Pressure Sensor (RPS). The PMX has support for up to 2 room pressure sensors (RPS) and can simultaneously monitor a primary and secondary (Ante) room.

The Price Tracking Controller (TC) is designed for tracking pair solutions to provide precision volumetric offset control in operating rooms and critical patient care spaces. This valve mounted controller includes full reheat control and the convenience of native BACnet communication.

The Room Pressure Controller (PC) is designed to provide intelligent room pressure control and monitoring of critical spaces. Multiple strategies are available including direct pressure control, volumetric offset, and a hybrid which offers the advantages of both.

All controllers and monitors use a local LCD Display (RPI). The RPI features visual and audible alarms signaling unsafe conditions with illuminating sidebars provide 180 degree visual status from anywhere in the corridor.

Laboratory applications use the healthcare controls and monitors but add products specifically designed for the unique environments found in the laboratory.

The Venturi Valve (VV) is a mechanically pressure independent control valve designed specifically for room pressure and fume hood control applications. The internal plunger assembly ensures the valve will respond to changes in duct static pressure in less than one second, while turndown ratios in excess of 20:1 serve to maximize energy savings in unoccupied or minimum flow set-points.

The Laboratory Space Controller (LSC) is designed for laboratory applications that require airflow and temperature control using a dedicated system that ties into the fume hoods within the space. The digital controller maintains a constant volumetric offset between the supply, general exhaust and fume hood air valves in the VAV system to ensure accurate control of directional airflow. Fume hood controllers are daisy chain wired to the controller and the local network uses Price M-Net for a less than 1 second speed of response between the controllers.

The Fume Hood Controller (FHC) is designed to control face velocity on variable volume fume hoods with audible and visual indicating alarms. The controller supports multiple air control devices including Venturi valves, LDV exhaust valves and Variable frequency drives. The Fume Hood Monitor (FHM) is designed to provide intelligent monitoring of fume hoods with native BACnet communication.

Price Critical Controls’ Presence Sensor (PS) is a low profile surface mount microwave sensor, utilizing Doppler shift radar to detect motion down to ¼” per second.
