1. Plates of Heat Exchangers

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. PHE Frames

Description

Plate Heat Exchanger Frame consists of plate heat exchangers, balance tanks, centrifugal sanitary pumps, hot water units (including steam lines, hot water injectors), brackets, and instrument boxes to Sterilize and coolfor milk or other heat sensitive liquids.

The material to be treated enters the balance tank of the Plate Heat Exchanger Frame first, and is sent to the heat exchanger through the centrifugal sanitary pump, and is preheated, sterilized, insulated, and cooled. If the material does not reach the sterilization temperature, the instrument controls the pneumatic reflow. The valve is reversed and returned to the balance tank for reprocessing. The material sterilization temperature is automatically controlled and continuously recorded by the instrument control box to monitor and inspect the sterilization process.
