Modine introduces its Hot Dawg H²O as an extension of the gas/propane Hot Dawg line. The Hot Dawg H²O is the first hydronic unit heater to have no moving external parts, making it a perfect fit for places such as a garage or warehouse. The unit’s design and low profile allow it to be rotated for either horizontal or vertical air discharge, giving users multiple installation options. The unit comes in two models – the HHD30, operating at a range of 23,700 to 39,200 Btu/hr and the high-capacity HHD45, operating at a range of 23,900 to 56,800 Btu/hr at 180°F of entering water temperature. The HHD45 also includes a speed control that allows the user to receive a range of 425 to 710 CFM.
