1.Heat Transfer Plates of PHE

Plate Features

We successfully merged many years of experience with industry leading research to develop its N series Gasketed Plate Heat Exchangers (“GPHEs”). These versatile models are suitable for a wide range of applications in these industries – Petrochemical, HVAC, Chemical, Power, Sugar, Renewable Energy, Food, Marine, Heavy Industry & Mining, and Industrial Refrigeration.

The heat transfer plates comprise of the following three types.

1. D-Plate (First heat transfer plate between the S, L, C, and E-Frames)
2. E-Plate (Last heat transfer plate between the S, L, C, and E-Frames)
3. Channel plates (Heat transfer plates except for the D-Plate and E-Plate between the S, L, C, and E-Frames)

A-Plates are fliped upside down to be used as B-Plates. The opposite is the same.(Excluding some models)


       N Series GPHEs feature an advanced frame design with a wide variety of plate material choices, configurations, and port sizes. The interior N Series plates are the most technologically advanced heat transfer plates on the market with features for efficient processing of all products, including those with high viscosities and fouling tendencies making the N Series the superior choice for your most challenging heat transfer specifications.

1. OptiWave – Plate Pattern

       Unique plate corrugation pattern allows even flow distribution across the entire plate surface thereby maximizing heat transfer while minimizing fouling rates, plate count, and cost.

2. Gaskets

       Gaskets work in perfect combination with our plates to ensure worry free operation. Our chamfered opening allows each gasket to settle into position and also prevents the lock tab from being severed. Gaskets can be easily installed without tools or adhesive and self-seat during closing. It takes just seconds to replace a gasket making maintenance quick and easy.

3. PosLoc – Assembly

       PosLoc plate design allows the GPHE plates to self-align and tightly seal every time the unit is closed. This feature virtually eliminates plate pack snaking, even if the frame is out of alignment and after repeated servicing. This distinctive feature provides you with years of stress free maintenance and operation.

4. One Frame For All

       Even if the medium or requirement changes, there is no greater flexibility. All of the N series plates can be used in the same frame with varying numbers of plates.

2. Gaskets of Heat Exchangers

Gasket Features

The plate gaskets comprise of the following four types.

– D-Gasket (Installed to the D-Plate port hole)

– E-Gasket (Installed to the E-Plate port hole)

– Channel gaskets (Gaskets installed to the front surfaces of heat transfer plates other than the D-Plate)

– Distance piece (String gasket that fills the gasket groove on the D-Plate or E-Plate)

“A-Plate channel gaskets” are fliped upside down for Trapezoidal flow or fliped horizontal and upside down for Diagonal flow to be used as “B-Plate channel gaskets”. The opposite is the same.


       In order to meet the immediate needs of our clients, we maintain a sizable inventory of plates and gaskets for the most popular makes and models. Additionally, at the client’s request, we will inventory the specific plate/gasket combination required for a plate pack swap.

For plates and gaskets that we do not have in our inventory, delivery times will vary …

  • New OEM plates will normally require 2 to 12 weeks depending upon the quantity and material of construction.
  • Virtually all gaskets are available in 1 to 2 weeks in any of the following materials:
  • NBR
  • HNBR
  • EPDM
  • Food Grade EDPM
  • Butyl
  • Viton G
  • Hapalon
  • Neoprene

3. Welded Plate heat exchangers

The KºBloc is a fully-welded plate heat exchanger that is used above all in the oil and gas industry, the chemical industry as well as in the petrochemical sector. The solidly bolted frame consists of four columns, top and bottom heads as well as four side panels. These side panels can be detached swiftly and allow free access all the way around for the thorough and easy cleaning of the fully-welded plate package. Two different plate corrugations are available. Chevron corrugation enables effective heat transfer. In contrast, double dimple corrugation is the first choice for highly viscous or solid containing media as well as for vacuum applications.


  • fully welded plate pack
  • for applications at temperatures up to 400°C and pressures up to 50 bar
  • small footprint and low installation cost
  • access to both media sides
  • easy cleaning thanks to unproblematic opening of the apparatus

4. Semi Welded Plate Heat Exchangers


Applications Heating and cooling of aggressive media. Duties in refrigeration installations.The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of the two fluids between which heat transfer will take place. The plate pack is assembled between a fix frame plate and a movable pressure plate and compressed by tightening bolts. The semi-welded plates combine the flexibility and serviceability of the gasketed heat exchangers with the assurance against leakage of the welded heat exchangers. In the plate arrangement, every other channel is welded, and every other channel is gasketed. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program. The plate corrugations promote fluid turbulence and support the plates against differential pressure.


The frame plate and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar,both of which are fixed to a support column. Connections arelocated in the frame plate or, if either or both fluids make morethan a single pass within the unit, in the frame and pressure plates.

5. Ammonia Plate Heat Exchangers


T10 eliminates the compromise between efficiency and pressure drop. With the improved design, we can better accommodate uneven flows, making it possible to optimize the performance of the heat exchanger according to its specific position in your processes.

The result is up to 30% higher efficiency and reduced fouling for reliable, cost-effective performance. And that’s just the start.

Whatever the application, T10’s truly sustainable, energy-saving design creates additional possibilities to meet environmental targets. And the new plate concept ensures lower total cost of ownership thanks to a smaller footprint and reduced maintenance needs.

6. Brazed plate Heat exchangers Exchangers


Low operational costs and very high performance make the gasket-free brazed plate heat exchangers optimal choices, even if your system has large temperature swings, or varying or constant pressure.

Brazed plate heat exchangers are one of the most efficient ways to transfer heat. They are designed to provide unparalleled performance with the lowest life-cycle cost. Choosing brazed technology for your next heating or cooling project will bring many benefits, including savings in space, energy, and maintenance.



Our BPHEs are extremely compact compared with other technologies. The footprint can be as little as one tenth that of a shell & tube heat exchanger or half that of a gasket PHE.


With no need for gaskets or supporting equipment, about 95% of the material is used to transfer heat. The highly turbulent flow also enables you to use small temperature differences efficiently.


The robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance and operational downtime.
