The Direct OEM Replacement for UBC H35G & H75G Glycol Chillers

Restore your cooling system to factory specifications with the Totton SPC42 (PV42). As the original equipment manufacturer (OEM) part for UBC’s most popular mid-sized chillers, this pump is designed for a drop-in installation—no bracket modifications or wiring workarounds required.

If your current chiller is struggling with "warm" towers or your glycol bath has frozen over, the SPC42 is the essential component needed to restore circulation and maintain your ice bank.

Critical Compatibility

This unit is the exact replacement part for the following UBC Group models:

• H35G (1/3 HP Glycol Chiller)
• H75G (3/4 HP Glycol Chiller)
• Cross-reference part numbers: PV42, SPC42/12, V-30

Why This is the Correct Replacement

When replacing a pump in a pressurized glycol system, "close enough" isn't good enough. The SPC42 is chosen by UBC for three specific reasons:

1. Vertical Lift (Head Height): Rated for a 12-meter head, it provides the specific pressure needed to overcome the resistance of long-draw insulated trunk lines without straining the motor.
2. Agitator Blade Integration: Unlike standard utility pumps, this features a specialized lower impeller that keeps the glycol bath in constant motion, preventing the evaporator coils from "icing up."
3. Thermal Protection: Includes an internal safety cut-off. If your glycol levels drop and the motor runs hot, the pump shuts down before it burns out.

Installation & Troubleshooting

Is it time to replace?

• Signs of Failure: A humming sound without liquid movement, visible leaking from the top of the pump shaft, or a "tripped" breaker on the chiller unit.
• Installation Tip: Before installing the new PV42, ensure the glycol bath is free of debris. Small fragments from a failed previous pump can jam the new impeller immediately upon startup.

Warning: Using a glycol concentration below 30% can cause the bath to slush, putting high-viscosity stress on the motor and leading to premature failure of your new replacement part.
