Condensate Return Units for Commercial & Industrial Steam Systems

ePumps supplies condensate return units engineered to improve boiler efficiency, reduce chemical and water costs, and maintain reliable condensate handling across demanding steam applications.

Features & Construction

Our condensate return units include:

  • Heavy-duty steel or stainless-steel receivers

  • Simplex or duplex pump assemblies

  • High-temperature mechanical seals

  • Silicon bronze impellers

  • Square D controls and float mechanisms

  • Multiple HP, voltage, and discharge options

Applications

Condensate return units are essential in:

  • Commercial boiler rooms

  • Industrial process steam loops

  • Manufacturing and production facilities

  • Institutional buildings

  • Large-scale HVAC systems

How to Select the Right Unit

When choosing a condensate return unit, consider:

  • Tank size: Sized for normal return flow + surge

  • Pump capacity: Must match condensate return rate

  • Material: Stainless steel for corrosive or high-purity condensate

  • Space requirements: Compact vs. high-capacity tanks

  • Connection sizes: Vent, overflow, discharge, and electrical

If you’re unsure which size or configuration you need, our experts can guide you through selection.

FAQ's

What does a condensate return unit do?

It collects and stores condensate before pumping it back to the boiler system to reduce fuel and water consumption.

Do I need a simplex or duplex unit?

Simplex works for small systems; duplex is recommended for larger steam loops or redundancy needs.

When should I choose stainless steel?

Choose stainless when dealing with corrosive condensate or strict purity requirements.

How do I size the tank correctly?

Tank size should be based on system load with extra capacity for surges during heating cycles.

Can these units be used in industrial settings?

Yes — many models are rated for high-temperature and continuous industrial use.
