Rated at 600 CFM, it ships in a right-hand configuration and features a 3-row cooling coil sized for light commercial and residential hydronic systems. The unit operates on 120 VAC single-phase power, draws 1.9 amps, and is driven by a 1\/8 HP blower motor spinning at 1,550 RPM. No refrigerant is required. Licensed HVAC technicians and mechanical contractors install this unit as part of a complete hydronic system, typically in ceiling plenum spaces where horizontal orientation conserves headroom.\u003c\/p\u003e\n\u003cp\u003eThe 450603R belongs to the HBC Series and is intended for horizontal ceiling-mount installations in buildings served by chilled water or hot water hydronic distribution systems. Its compact footprint — 40.1 inches long, 21.0 inches wide, and 10.0 inches tall — makes it suitable for low-profile ceiling cavities in offices, retail spaces, hotels, and multi-family residential construction. The right-hand configuration determines coil connection and drain pan orientation, so field verification of piping layout is required before ordering.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHydronic operation — no refrigerant required, compatible with chilled water and hot water systems\u003c\/li\u003e\n  \u003cli\u003e600 CFM airflow rating with a 3-row cooling coil for effective sensible and latent heat transfer\u003c\/li\u003e\n  \u003cli\u003eRight-hand configuration for specific piping and drain pan orientation\u003c\/li\u003e\n  \u003cli\u003e1\/8 HP, 1,550 RPM blower motor on 120 VAC single-phase, 60 Hz power\u003c\/li\u003e\n  \u003cli\u003eHorizontal ceiling-mount design fits low-profile plenum spaces\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA as part of the First Company HBC Series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in hydronic heating and cooling systems as part of the First Company HBC Series of horizontal ceiling-mount air handlers.

Shut off the hydronic supply and return lines and de-energize the circuit at the breaker before making any connections. Follow local mechanical codes and manufacturer piping guidelines for proper supply, return, and condensate drain connections. Verify structural ceiling support is adequate for the unit weight prior to mounting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HBC Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEquipment Type\u003c\/strong\u003e: Hydronic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow\u003c\/strong\u003e: 600 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Coil Rows\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 1.9 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower Motor HP\u003c\/strong\u003e: 1\/8 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower RPM\u003c\/strong\u003e: 1,550 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: None required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 40.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 21.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 54.0 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FIRST COMPANY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 450603R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FIRST COMPANY","offers":[{"title":"Default Title","offer_id":51383485694258,"sku":"450603R","price":895.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670594.webp?v=1782598132","url":"https:\/\/voomisupply.com\/products\/first-company-450603r-hydronic-ceiling-mount-air-handler","provider":"Voomi Supply","version":"1.0","type":"link"}
