It delivers 36,000 BTU\/h of DX cooling capacity and 47,800 BTU\/h of hot water heating capacity, making it a dual-function unit suited for spaces where a single ceiling coil must handle both seasons. The unit uses a piston-type metering device and ships configured for R-410A refrigerant only. A two-speed PSC motor drives airflow, and the unit includes a 120\/24-volt relay and transformer. This coil is intended for servicing existing Aquatherm installations, not new construction pairings outside its rated refrigerant and water system requirements. Licensed HVAC technicians perform installation and commissioning.\u003c\/p\u003e\n\u003cp\u003eThe 37CDXW is ceiling-mounted and fits residential and light-commercial applications where Aquatherm-style fan coil systems are already in service. The unit combines a two-row hot water heating coil with DX cooling in one cabinet, reducing the need for separate terminal equipment. No pump is included. Hot water heating performance is rated at 4.8 GPM at 180 degrees F. The unit is intended for use with R-410A exclusively and is not compatible with legacy refrigerants. It is appropriate for replacement installations in existing Aquatherm ceiling fan coil systems where the original equipment used the same refrigerant and hydronic heating configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e36,000 BTU\/h DX cooling capacity at 3.0 tons with R-410A piston metering device\u003c\/li\u003e\n  \u003cli\u003e47,800 BTU\/h hot water heating capacity rated at 4.8 GPM at 180 degrees F\u003c\/li\u003e\n  \u003cli\u003eTwo-speed PSC motor for ceiling-mount airflow distribution\u003c\/li\u003e\n  \u003cli\u003eIntegrated 120\/24-volt relay and transformer included\u003c\/li\u003e\n  \u003cli\u003eInsulated and coated galvanized drain pan for corrosion resistance and condensate management\u003c\/li\u003e\n  \u003cli\u003eLiquid line connection: 3\/16 inches OD suction line connection: 3\/4 inches OD\u003c\/li\u003e\n  \u003cli\u003eIntended for servicing existing Aquatherm equipment only — not for new-system applications outside original design parameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement fan coil for existing First Company Aquatherm ceiling fan coil systems using R-410A refrigerant and hot water heating.

Power down all electrical circuits and shut off the hydronic supply and return lines before removing the existing coil. Verify that existing refrigerant line sets, drain pan connections, and electrical service match the dimensions and ratings of this unit before mounting. Do not use this coil with refrigerants other than R-410A.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Capacity\u003c\/strong\u003e: 36,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 47,800 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetering Device\u003c\/strong\u003e: Piston-type\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFan Motor Type\u003c\/strong\u003e: PSC, two-speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120\/24 volts (relay\/transformer included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Fuse\u003c\/strong\u003e: 15 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHot Water Flow Rate\u003c\/strong\u003e: 4.8 GPM at 180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Connection\u003c\/strong\u003e: 3\/16 inches OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Connection\u003c\/strong\u003e: 3\/4 inches OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Dimensions\u003c\/strong\u003e: 57.13 inches W x 21 inches D x 10 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 105 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrain Pan\u003c\/strong\u003e: Insulated, coated galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Ceiling\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: 37CDXW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FIRST COMPANY","offers":[{"title":"Default Title","offer_id":51525389746482,"sku":"37CDXW","price":2103.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d714bb582c89769a02ccb46fbf8ee7d0.webp?v=1785472501","url":"https:\/\/voomisupply.com\/products\/first-company-37cdxw-aquatherm-ceiling-fan-coil-3-ton-r-410a","provider":"Voomi Supply","version":"1.0","type":"link"}
