New Plate & Frame Heat Exchangers

Polaris Quality demands careful attention to the materials and craftsmanship in every heat exchanger they make.  Here's why you can expect superb efficiency, low maintenance, and long life from your Polaris unit.

 

PLATE-LOCK POSITIVE ALIGNMENT SYSTEM

A Special locking lip secures the connection between plates, keeping them precisely aligned and tightly sealed even at high working pressures. A Polaris exclusive!

PLATE SEALING SYSTEMS

Polaris provides the proper plate sealing system for wide range of applications. Choose from glued gaskets or Clip-Tite glueless gaskets.

 

HEAVY-DUTY FRAME HEADS

Polaris frame heads are built thicker to deliver even pressure to the plate pack. They eleminate the need for inferior welded-frame reinforcements. Opening the exchanger is fast and easy.

 

VERSATILE CONSTRUCTION

Polaris heat exchangers feature bolted construction for strength and accessibility. They can be assembled at the job site, and are easily expanded.

 

PROTECTIVE SHROUD

This safety feature complies with all applicable OSHA requirements; OSHA shrouds are included with every heat exchanger. Polaris also offers insulated shrouds to avoid condensation in humid locations.

 

HEAT TRANSFER PLATES

Polaris quality begins in their plates. They're constructed of rugged, heavy-duty stainless steel and pressed in designs that precisely fit a wide range of heat transfer applications. See our spec sheet for additional available plate materials.

 

SAFETY-PAIR DOUBLE WALL PHEs

Where reliable separation of primary and secondary fluids is required, Polaris Safety-Pair PHEs deliver enhanced protection. For domestic hot water, dairy or other food processing, chemical manufacturing, or other critical applications, Safety-Pair PHEs from Polaris keep the fluids separated even if there's a plate failure. (Paired plates create an air space, allowing leaks to be seen from the outside. Any such leaks reach the atmosphere, either between plates or from the drain channels in teh inlet/outlet areas. Media can never mix, so the risk of contamination is minimized.)

 

FREE-FLOW PLATES

The Polaris Free-Flow Plate Heat Exchanger accommodates viscous fluids or those containing viscous fluids or those containing fibrous materials. Its wide-channeled, horizontal-ribbed patter with no metal-to-metal contact allows the free passage of particles that can block the flow in other heat exchangers.

 

SEMI-WELDED PHEs

Polaris semi-welded plate heat exchangers handle the jobs conventional plate exchangers can't touch -  including ammonia refrigeration and aggressive process fluids. Our semi-welded PHEs offer

  • Laser-welded plate cassettes
  • Welds running outside the gasket groove for corrosion protection and increased heat transfer area
  • Superior sealing capability
  • Improved sealing under higher pressure
  • Easy cleaning

 

SANITARY HEAT EXCHANGERS

For food, dairy, and pharmaceutical processing, sanitary heat exchangers from Polaris combine low maintenance, high efficiency, and reliable separation of fluids. Plate gaps in these exchangers are sized to reduce fouling; the main pattern creates the needed turbulence for effective heat transmission.

 

FRESH WATER DISTILLING SYSTEMS

Utilizing the heat from diesel engine jacket cooling water, the Polaris Fresh Water Distiller evaporates seawater to produce pure drinking water. Contact us for details.
