MAKE-UP UNITS STANDARD AND HEAT RECOVERY

Rooftop ventilation units with energy recovery, heating and cooling and designed to handle up to 100 percent of outside air and can be applied to dedicated outdoor air systems, variable air volume systems, and constant volume systems

MULTI-ZONE HEAT PUMP SPLIT SYSTEMS

Multipoint systems can serve up to eight rooms/zones from a single outdoor condensing unit. With indoor unit options consisting of wall/ceiling ductless fan coils, build- in ducted units or a combination of both multi-systems offer many possible connections combinations, creating a flexible, powerful and energy efficient system.

SINGLE ZONE HEAT PUMP SPLIT SYSTEMS

These one-to-one systems offer connectivity with a variety of indoor units for a simple solution for almost any applications including residential whole house/apartments, light commercial offices

COMMERCIAL KITCHEN HOODS EXHAUST

In commercial kitchens with banks of ovens, grills and fryers , adequate ventilation is essential to deal with the effect of heat, smoke, odors.Installation of 14 Ga. welded exhaust ducts with rooftop exhaust fans and make -up units to compensate for the air ventilation from the kitchen space.

GARAGE EXHAUST
CO SYSTEMS

CO (carbon monoxide) controlled VFD driven garage exhaust system typically including the following equipment: CO sensors, Control Panel, Variable Frequency Drive (VFD) to control exhaust fan motor.

GENERAL EXHAUST
SYSTEMS

“Energy Star “ certified exhaust fans including a large variety of sensors and timers, accessories to provide proper ventilation in bathrooms, kitchens, laundry rooms, hallways, common areas

VRV HEAT RECOVERY

The same advantage as VRV heat pumps systems plus simultaneously cool and heating zones within a building to provide energy savings, heat recovery operations through the use of the BC controller.BC controller is the technological heart of the system, it works s in unison with the outdoor unit to provide simultaneous cooling and heating. This means less work is required of the outdoor unit, which translates into energy savings and increases overall capacity

EMS CONTROLS

Daikin, Mitsubishi, Fujitsu, Trane equipment can be monitored and controlled with centralized control panel also all supply/ exhaust fans, makeup units can be connected to EMS system . Allows daily remote monitoring and control with the Web/Email software option that can be accessed via local area network.

VRV HEAT PUMP SYSTEMS

Multiple indoor fan coils connections to a single refrigerant network. At the heart of the condensing unit is a high-efficiency variable speed ‘inverter” compressor compelled with inverter fan motor for superior system part load performance. The compressor capacity is modulated automatically to maintain a constant suction pressure , which varying the refrigerant volume to precisely deliver cooling or heating load requirements.
