Bell & Gossett 104302 Ecocirc XL 36-45 Iron Body Circulator

Control commercial heating and cooling loops with Bell & Gossett 104302 ecocirc XL 36-45, an ECM wet-rotor circulator for 208–230 V single-phase service. The cast-iron body suits closed-loop hydronic systems, while proportional-pressure, constant-pressure, and fixed-speed modes give technicians several ways to match circulation to system demand. Confirm the control wiring, connection style, and operating range before installation.

The electronically commutated motor operates at 1/6 HP with a 20 W to 150 W power range and supports the XL 36-45 performance envelope. Modbus RTU and BACnet readiness allow integration planning with compatible building controls, while the supplied data lists up to 36 feet of head and 45 GPM flow. Verify communication requirements, system curve, dimensions, and clearance against the current submittal.

Why Choose Bell & Gossett 104302 ecocirc XL 36-45

The ecocirc XL 36-45 is aimed at commercial hydronic systems that need electronically controlled circulation rather than one fixed operating speed. Its multiple control modes make commissioning more adaptable.

- Build: ECM motor, cast-iron body, wet-rotor arrangement, and digital control capability provide defined operating features.
- Value: Adjustable control and a 20 W to 150 W power range can reduce unnecessary pump energy during lower demand.
- Audience: Suited to commercial HVAC contractors, building-automation technicians, facility engineers, and hydronic retrofit teams.

Applications & Use Cases

Use Bell & Gossett 104302 ecocirc XL 36-45 for commercial heating and cooling loops, closed hydronic circuits, and compatible 208–230 V systems. Verify the current submittal for exact dimensions, weight, connection type, and flange-to-flange length, then check control-panel access, communication wiring, valve clearance, and service space before installation.

Warranty & Support

- Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with the seller.
- Match SKU 104302, ecocirc XL 36-45 model, 208–230 V supply, and control requirements before ordering.

Flush the loop, purge air, verify the 208–230 V supply, and configure the selected control mode before startup. Confirm communication wiring where used, then monitor flow, head, power draw, vibration, and temperature during commissioning.
