PU Foam Insulation Spraying for Water Heaters, Refrigerators, and Solar Water Heaters

PU Foam Insulation for equipment such as water heaters, refrigerators, and solar water heaters plays an important role in improving operational efficiency and energy savings.

The PU insulation layer helps minimize heat loss and maintain stable temperatures throughout the usage process. For water heaters, the insulation layer helps retain heat for longer periods, reducing electricity consumption required to reheat the water. Refrigerators also benefit from PU insulation by maintaining cooling efficiency, reducing energy consumption, and improving food preservation performance.

In particular, for Solar Water Heater systems, the PU insulation layer not only helps optimize heat retention efficiency but also maintains water temperature during periods without sunlight.

PUSONMAI COMPANY provides custom PU insulation processing and manufacturing services according to customer requirements.

What is the insulation layer inside a water heater and a solar water heater?

Inner Tank:

The inner tank is typically manufactured from stainless steel or premium enamel-coated steel used in food-grade technology. It is welded using high-frequency welding technology, ensuring that the water quality remains unaffected by heat reaction during use.

Insulation Layer:

The insulation layer is made from PU Foam Insulation with approximately 55 mm thick polyurethane foam injected under high pressure. Under stable temperature conditions, it provides excellent thermal insulation and maintains water temperature for an extended period (up to approximately 72 hours) with minimal heat loss.

Outer Casing:

The outer casing is made from stainless steel or electrostatically powder-coated steel with standard thickness, providing durability, aesthetic appearance, and reliable performance even in harsh environments and coastal areas.
