  • GreenHeat Direct Gas-Fired Heating System

    The GreenHeat system uses 100% outside air and direct gas-fired heaters. 100% outside air provides slight building pressurization, offsetting infiltration. The direct gas-fired burner provides 100% post latent heat efficiency. Together the direct gas-fired burner and positive building pressure provide a heating system which requires significantly less energy than an air rotation unit to heat a space. The GreenHeat system uses a high velocity discharge, reducing stratification and providing even heating.

  • Greenheck's Water Wizard

    Greenheck's Water Wizard provides complete evaporative cooling control. The Wizard measures the outside temperature and humidity then adjusts the water supply to provide only the water needed for maximum evaporative cooling. On cool or humid days, the Wizard knows the evaporative cooling potential is low and reduces the water supply to save you money. On hot or dry days, the wizard increases the water supply to meet the increased evaporative cooling potential, providing you with the most cooling possible.
