Capacities
Based on 180° entering hot water and 0° entering air. Water flow rates (GPM) shown were determined by selecting water temperature drops and coil circuiting resulting in efficient heat transfer values without excessive pressure drop. Contact your local Hastings sales representative for coil capacities at other conditions.
