Daikin, Minneapolis, Minnesota, announced the expansion of its SmartSource Compact water source heat pump (WSHP) product line, adding a horizontal configuration to make the technology a fit for a broader range of applications. SmartSource Compact heat pumps are designed to provide commercial contractors and facility managers with a low-cost alternative to more expensive and larger WSHPs. Now with vertical and horizontal configurations, the compact WSHPs are ideal for new construction and retrofits where space and budgets are limited. They can be configured for boiler tower or geothermal applications that are often found in schools, offices, lodging, condominiums and retail facilities
