Configurable Packaged Air Handling Equipment - Valent Air

1 PRODUCTS VPR SERIES VPRX SERIES VPRE SERIES VPRP SERIES VPRC SERIES VRC SERIESC onfigurable Packaged Air Handling Valent ADVANTAGE Quality, reliability, flexibility, and supportQUALITYT horough factory run-testing. After assembly, every unit is energized and rigorously tested for an average time of 90 minutes. Testing verifies proper operation: Refrigeration testing at multiple conditions to evaluate superheat and subcooling performance Heat testing throughout heating operating range Electrical testing of component continuity and phasing Supply and exhaust fan testing for proper operation Valent manufactures highly Configurable Packaged air Handling systems. At our core is a commitment to initial quality, long-term reliability, application flexibility, and dedicated product casing sizes and pre-engineered options fit a wide range of applications. Multiple heating and cooling configurations allow stand-alone operation or connection to a central system Multiple energy recovery options Multiple duct connection optionsVPR Series with 352 casing, EC-driven condenser fans, 10:1 turndown gas heat, and modulating hot gas reheatOn the cover: VPRC Series with 210 casing, enthalpic core heat exchanger, indirect gas heat, electric preheat, and modulating hot gas reheatRELIABILITYSafe, consistent lifetime performance.

2 Reliability is enhanced through: Best-in-class components including Digital ScrollTM and inverter scroll compressors, modulating direct-drive fans, and 2" foam injected double wall casings Low maintenance requirements including energy recovery options with no moving parts Dependable controls platformsSUPPORTD edicated pre- and post-sale application engineering support. We are here to help you with: Design decisions Installation guidance Ongoing operation and maintenance Multiple preconfigured platforms and application-specific solutionsAIR HANDLERSVPR AND VPRX SERIESThe VPR and VPRX are capable of cooling, heating, and dehumidifying a wide range of entering air loads up to 100% outdoor air. In applications requiring powered exhaust, the VPRX offers modulating exhaust fans for pressure relief and economizer RECOVERY AIR HANDLERSV alent's rotating enthalpy wheels recover up to 70% of return-air energy, and slide out for easy access. Valent 's highly Configurable air Handling systems are available in five casing sizes and include multiple cooling, dehumidification, heating, energy recovery, control, filtration, and duct connection 's flat plate heat exchangers have no moving parts and require minimal maintenance.

3 They both have extremely low airstream cross-contamination flat plate heat exchangerEnthalpic core heat exchanger detailVRC Series remote condenser with EC-driven condenser fan optionVPRE SERIESThe VPRE expands upon the VPR Packaged platform to include an air-to-air enthalpy wheel and powered exhaust fan section. Two enthalpy wheel types are available: A lightweight polymer wheel with silica gel desiccant, and an aluminum wheel with molecular sieve SERIESWhen recovering sensible and latent energy is a priority but the maintenance requirements of an enthalpy wheel are unwanted, the VPRC with its enthalpic core heat exchanger is an excellent alternative. The enthalpic core heat exchanger has a exhaust air transfer ratio (EATR) as determined by AHRI 1060, and can safely handle accumulated condensate without sustaining frost SERIESIn applications where sensible-only energy recovery is desired, the VPRP delivers with an all-aluminum flat plate heat exchanger that has a low pressure drop and an extremely low cross-contamination rate.

4 Although commonly used in dry climates, the VPRP is also effective in high humidity or polluted spaces where airstream cross-contamination is CONDENSERVRC SERIESVRC remote condensers can be paired with select Valent air handlers. Compressors remain mounted in the indoor air handler for reliability and piping simplification, eliminating the need for a third refrigeration line on circuits with hot gas VPRE and VPRC Series air handlers are AHRI 1060 Certified as Packaged energy recovery , COOLING, DEHUMIDIFICATION OPTIONS Multiple options for stand-alone operation or connection to a central systemHE AT ING INDIRECT GAS FURNACE Standard construction includes 409 stainless steel burner tubes appropriate for 100% outdoor air applications Modulation range: 5:1 turndown standard 10:1 turndown optionELECTRIC SCR-modulated electric resistance heaterT EMPER ATOR Hybrid heating system pairing a 5:1 modulating gas furnace with a small SCR electric heater for total capacity modulation On-board controls operate in one of three heating modes.
