Gasketed Plate and Frame Heat Exchanger

High-efficiency heat transfer. Flexible configurations. Easy maintenance. All in a compact, field-proven design.

Built for performance and flexibility, LHE’s gasketed plate and frame heat exchangers deliver efficient thermal transfer, easy serviceability, and cost-effective operation.

Every unit is engineered to your specs and designed to evolve with your process over time.

Designed to handle real-world process demands

Our gasketed design separates hot and cold fluids using thin, corrugated plates — each sealed by a replaceable gasket. These plates are stacked into a frame that’s easy to open, adjust, and clean.

Add or remove plates to match changing capacity needs. Perform gasket swaps without disassembling the entire unit. It’s a design made for uptime, adaptability, and total service access.

Plate and gasket technology

As two fluids pass through alternating plate channels, heat transfers through the thin metal surface — no mixing, no direct contact.

The corrugated pattern creates turbulence at low flow rates, increasing thermal efficiency and reducing fouling. That means you get better heat recovery with less energy and fewer cleanings.

Choose the right plate for your process

High-theta Plate

Maximizes heat transfer
High turbulence = better efficiency
Ideal for close temperature approaches
Higher pressure drop

Low-theta Plate

Designed for gentle flow
Lower heat transfer coefficient
Supports higher temperature differences
Lower pressure drop

Flexible flow design

Three types of channels are available with the high theta and low theta plates.

High Channel

Two high-theta plates for max turbulence and heat transfer.

Low Channel

Two low-theta plates for low resistance and smooth flow.

Medium Channel

One high and one low-theta plate for a balance of efficiency and pressure drop.

Engineered for your performance needs

High efficiency

Corrugated plates create turbulence even at low flow, achieving up to 5 times the thermal efficiency of shell-and-tube exchangers.

Compact footprint

Our Gasketed Plate and Frame Heat Exchanger are 20–30% smaller than traditional designs. Fit more performance into less space.

Low fouling

Turbulent flow minimizes build-up and extends maintenance intervals.

Flexible flow paths

Configure counterflow, co-current, and pressure drop options to match your process.

Minimal heat loss

Tight stacking and insulation keep thermal losses to a minimum.

Close temperature approach

Maximize heat recovery with plate geometry optimized for minimal ΔT.

Low maintenance cost

Our Gasketed Plate and Frame Heat Exchanger is easy to disassemble and reassemble for gasket or plate replacement. Adding plates to increase capacity can be done quickly with minimal downtime.
