SunEarth Empire EP-40-2 Solar Thermal Collector

Part Number: EP-40-2 | Nominal 4 × 10 ft

The SunEarth Empire EP-40-2 collects solar heat for residential and commercial water-heating systems. Its copper absorber and fluid passages transfer collected energy into circulating water or an appropriate heat-transfer fluid.

Moderately selective black paint, low-iron tempered glass, and an anodized aluminum casing combine solar collection with durable outdoor construction. Compatible system designs include direct circulation, glycol, and drainback configurations, selected for the application and climate.

Product Highlights

  • Copper absorber and piping: Conduct heat into the system fluid.
  • Black absorber coating: Moderately selective paint captures solar radiation.
  • Low-iron tempered glass: Admits sunlight to the absorber.
  • Insulated casing: Foam and fiberglass help reduce heat loss.
  • Integral mounting channel: Supports installation with compatible mounting components.
