PSHE, AdvantagesPSHE advantagesShell and Tube HEAdvantages:

Plate and Frame HEAdvantages:+ Compact size+ Low fouling tendency+ Close approach temps+ High pressure+ High temperature+ No gaskets

Disadvantages:

Disadvantages:- Low pressure- Low temperature- Gasket- Large size & weight- High fouling tendency

Plate and Shell HE+ Robust construction+ Minimized maintenance+ High and low temperatures +550 / -196°C+ Compact size+ Close approach temps+ Efficient heat transfer

AdvantagesFully welded and strong construction-Designed to:- withstand high pressures and temperatures-

Able to withstand stress variations and thermalshocks-The construction allows the plates to expand andcontract with thermal expansion and contraction

PSHE well suited for cryogenic use-Round plate highly resistant to thermal stressesMaterial fully 316/316L and PTFEMedia either refrigerant or glycol. Temperatures and channel flow ratedesigned to counter freezing potential.
Temperature difference >250°CSuperheating of gas to above room temperature without separatesuperheater unit.

RESISTANCE AGAINST THERMAL & MECHANICAL STRESSEasy to maintain-No gaskets with fully welded construction-

Low fouling-

Stretchable plate pack as an option-

Efficient and easy cleaning systems foreven the toughest environments

Easy to maintainLess fouling with PSHElIn Shell and Tube heat exchangerlaminar flow allows deposition of dirtand particles on heat transfer surfacel

In Plate and Shell heat exchangerturbulent flow and high shearstress keep particles moving andheat transfer surface clean

Energy efficiency--

Effective heat transferHighly turbulent flow together with high shear stresskeeps particles moving enabling:o High heat transfero Low foulingScientifically sized and field tested circulationClose approach temperatures possibleTemperature crossover possible

Custom-made-Designed and manufactured according to customer needs-Accurate thermal sizing guarantees the best possible heatexchanger solution-

Years of experience in heat transfer and strong productdevelopment ensures robust and durable products for ourcustomers
