Working principle

How the technology transfers heat.

Corrugated heat-transfer plates form alternating hot and cold channels. Gaskets seal each channel and direct the two fluids, normally in counter-current flow, while heat passes through the thin plate wall.

Construction: Openable gasketed plate pack in a bolted frame
Flow arrangement: Normally counter-current
Capacity adjustment: Plates may be added or removed within frame limits
Cleaning: Mechanical opening or chemical CIP

Engineering explained

See what is happening inside the exchanger.

Product imagery is paired with technical context so buyers and engineers can understand construction, flow path and configuration—not just the exterior.

Exploded construction of a standard gasketed plate heat exchanger — 01
Openable frame and plate-pack construction
The front frame plate, movable pressure plate, corrugated plate pack, guide bar, support column and tightening bars form a serviceable exchanger that can be opened for inspection or capacity adjustment.

HEXNOVAS GPHE series

Three standard plate families, organized by flow geometry and duty.

The series structure groups the current HEXNOVAS model range by plate proportion and construction. It gives engineers a faster starting point while final plate pattern, channel depth and plate count remain duty-specific.

General industrial duty

B SERIES

Balanced industrial plates

BB30 · BB60 · BB100 · BB150 · BB200 · BB250 · BB300 · BB450Installed-reference review: M3, T5, M6, M10, M15, M20, M30 and T45 classes

The core HEXNOVAS GPHE family for utilities, HVAC, marine and general process duties. Balanced plate proportions combine a broad operating window with practical inspection, cleaning and capacity expansion.

Close approach & heat recovery

L SERIES

Long thermal-length plates

LB30 · LB60 · LB100 · LB150 · LB350Installed-reference review: TL6, TL10, TL15 and TL35 classes

Long, narrow plates provide more thermal length per pass. They are the starting point for close temperature approaches, heat recovery and duties where a longer flow path improves thermal effectiveness.

Preferred for steam condensation

S SERIES

Short-wide steam plates

SB60 · SB200Installed-reference review: TS6 and TS20 classes

The preferred HEXNOVAS geometry for steam condensation. Its short, wide flow path provides a large inlet area for high-volume vapour, keeps pressure drop low and supports rapid condensate removal. It also suits other high-flow duties where hydraulic capacity governs selection.

How to read the model code

Series identifies geometry; suffixes refine the configuration.

B / H frame: 10-bar and 16-bar frame-pressure classes
B plate: Standard channel depth for broad industrial duty
H plate: Deeper channel for lower pressure drop or fouling tolerance
P plate: Intermediate channel option where available

Model families are HEXNOVAS designations. Familiar installed-equipment dimensions can be used as a cross-reference starting point, but model equivalence is confirmed only after thermal, hydraulic, material and mechanical review.

Selection information

What our engineers need from you.

Provide fluid composition and concentration, flow rates, inlet and outlet temperatures, operating and design pressures, allowable pressure drop, connection sizes, cleaning method and maintenance clearance. Confirm plate and gasket compatibility with both the process and cleaning fluids at the design conditions; material names alone do not establish suitability.

Frequently asked questions

Key questions before product selection.

What is the difference between a gasketed plate heat exchanger and a plate-and-frame heat exchanger?

They normally describe the same openable construction: corrugated plates with gaskets are clamped in a bolted frame. The plate pattern, channel gap, gasket material and frame pressure class are selected for the duty.

When should titanium plates be used in a gasketed plate heat exchanger?

Titanium is commonly considered for seawater and chloride-bearing fluids after reviewing concentration, temperature, contaminants and operating conditions. Material suitability must be confirmed for the complete fluid chemistry.

Can the capacity of a gasketed plate heat exchanger be changed?

Often yes. Plates may be added or removed within the frame, connection and hydraulic limits. Any change requires a new thermal and pressure-drop check.

Which data is required to select a gasketed plate heat exchanger?

Provide both fluids, compositions, flow rates, inlet and outlet temperatures, operating and design pressures, allowable pressure drop, fouling tendency, plate material and gasket compatibility.
