Sierra Products

DOAS	Split System - Model ZFR
		Dedicated Outside Air System Rooftop AHU with dehumidification, heating, and filtration Utilizes external DX or existing CWS cooling source Integral indirect-fired heating with DHTD (patent(s) pending) Includes Patented AdaptAire™ DDC controls, integrates with most building control systems	The ZFR delivers high quality outside ventilation air for comfort and Indoor Air Quality in commercial buildings, with dehumidification, heating and filtration (up to MERV15) in a split system configuration. The ZFR allows engineers to satisfy load requirements more efficiently with higher ventilation rates while permitting conventional HVAC equipment to operate as originally designed.
DOAS	Integral Package Unit - Model DCV
		Dedicated Outside Air System Rooftop AHU with integral cooling, heating and filtration Built-in DX condensing unit Integral indirect-fired heating with DHTD (patent(s) pending) Includes Patented AdaptAire™ DDC controls, integrates with most building control systems	The new Sierra DCV is the most cost-effective way to provide cooling, heating and high-efficiency filtration (up to MERV15) of outside air for commercial building ventilation in a packaged unit. The DCV is the only packaged DOAS unit that delivers full ASHRAE 62.1 compliance, and up to 6 LEED points in a single product!
EVAP	Evaporative Cooling System - Model ZEC
		Heavy duty single-stage evaporative cooling Ideal for laundries and restaurants Up to 80% saturation efficiency Low Operating and Maintenance Costs	The ZEC evaporative cooling system is one of the most environmentally friendly ways to improve working conditions and productivity. Evaporative systems can cool at 20% the cost of mechanical air conditioning. The innovative Turbo-CEL™ evaporative cooling media provides efficient cooling using water, not refrigerants, reducing your carbon footprint. Capacities up to 23,000 cfm are available.
EVAP	Indirect/Direct Evaporative Cooling System - Model Aztec
		Multi-stage rooftop evaporative cooling system for make-up and ventilation As much as 30° drop at 100°/74° F design conditions Provides up to 119% saturation efficiency Performance far exceeding typical evaporative systems	The Sierra Aztec evaporative cooling system is the ultimate in energy efficiency, providing impressive reductions in supply air temperatures rivaling mechanical refrigeration. The Aztec uses a first stage integrated stainless steel cooling tower and cooling coil to provide cooled air to a second stage direct evaporative section, delivering performance of up to 30 EER. Available in sizes from 1500 to 37000 cfm, the Aztec is also available with a heating section up to 1.4 mbtu input.
DF-HEAT	Direct-Fired heating system - Model ZDF
		Direct-fired design delivers 100% combustion efficiency for space heating 2.5" of external static provides installation flexibility and handles long duct runs Certified to ANSI Standards Z83.4 and Z83.18 Includes Patented AdaptAire™ DDC controls, integrates with most building control systems	The ZDF Direct Fired systems are flexible, cost-effective units for indoor or outdoor space heating, make-up air, and ventilation applications. Superior tube frame construction and stainless steel burners deliver decades of reliable service. The ZDF from Sierra can provide up to 16,000 CFM of warm, fresh and clean air to your building.
