API SCHMIDT SIGMA 66/M66 Model Plate Heat Exchanger Gasket and
Plate for Water Heating
SIGMA 66/M66 Model Plate Heat Exchanger Basic Structure
Heat transfer plates are made by pressing thin sheets of corrosion
- resistant metal such as stainless steel or titanium, then set
them with seal gaskets and hang sand pile them on the guide bar.
The, plates are tightened with bolts between the fixed frame and
the movable frame. Here, there is a certain gap between the heat
transfer plates that allows liquid to flow. The liquid inlets and
outlets are in the fixed frame or the movable frame.

OEM & ODM PHE Plate Parameters
The plates are specially selected from various patterns so as to
achieve optimum area and cost effective heat exchanger for each
unit. These plates can be classified into three type, H type, L
type, Mix type.
Plate Corrugate
Low angle channel arrangement for lower allowable pressure drops
requirement applications;
Mixed channel arrangement for optional arrangement to gain the
optimized performance;
High angle channels arrangement for higher thermal performance and
allowable pressure drops requirement applications
The Standard Materials
304 Stainless Steel
This is the lowest cost heat transfer plate material. It has low
corrosion resistance and is usually only available in a thickness
of 0.5mm. This type of heat transfer plate is typically used in
HVAC applications.
316 Stainless Steel
This is the most common heat transfer plate material and is used in
many applications. 316 stainless steel has a high corrosion
resistance and is typically available in thickness from 0.5mm to
0.8mm.
Titanium
This type is very resistant to chemical attack, including most
acids, chloride, seawater and chlorine chemicals. This thickness of
titanium is usually from 0.5mm to 0.6mm.
Hastelloy C276
Other common names: Alloy C276, Hastelloy C, Inconel® C-276, Hastelloy C276.
Hastelloy C276 is a nickel-molybdenum-chromium superalloy with
tungsten added for excellent corrosion resistance in a variety of
harsh environments. Alloy C-276 is widely used in the harshest
environments such as chemical processing, pollution control, pulp
and paper production, industrial and municipal waste treatment, and
acid natural gas recovery. The thickness can range from 0.6mm to
0.8mm.
SMO 254
Sandvik 254 SMO is a high-alloy austenitic stainless steel
developed for use in seawater and other aggressive chloride-bearing
media. Thickness available from 0.6mm to 0.8mm.

Plate Heat Exchanger Features
Heat Transfer Plates
Each heat transfer plate is corrugated to various patterns to
increase its strength and heat transfer area. Furthermore, the
corrugation creates high turbulence and thereby achieve high heat
transfer coefficient. The plate is provided with passage hole on
each corner. Each plate is tight-sealed with a gasket fitted in its
peripheral groove.
Flow Channel
The plates are divided into A-plate and B-plate, and a passage is
formed between these plates. The high temperature fluid flows
alternately and in the opposite direction of the other fluid. Thus
high efficient transfer of heat is achieved through these plates.
A-plate when reversed would become B-plate. As such only one type
of plate can be used as A-plate and B-plate for most models.
Easy Maintenance
The plate heat exchanger can be easily opened for inspection and
maintenance by loosening the tightening bolts and nuts. Assembly
and opening of the unit are also easily performed.
Less Installation Space
The lightweight and compact construction saves the installation
space to 1/4 and the weight to 1/3 of shell & tube heat exchanger
respectively. In addition, lightweight and thin heating plate with
less liquidhold facilitates the installation work.
The Plate Heat Exchanger can be disassembled for cleaning without
piping work, while the shell & tube heat needs a additional space
for drawing out the tube bundle.
Plate Heat Exchanger Advantages
1. Heat transfer coefficient is about 2 times as high as that of
shell & tube heat exchanger. The condensing surface is always
secured and the heat transfer coefficient is improved because
condensate is immediately drained out.
2. To achieve much less vapor pressure drop than the conventional
Plate type Heat Exchanger, special consideration of plate
characteristic is taken in contribution.
3. Cooling water consumption is about half of heat exchanger.
4. The use of gasket is selectively used and it expands the
application to wide field.
5. Easy change of condesing capacity by increase or reducing the
number of plates.
6. Because of inlet and outlet connections at the same side, SIGMA 66/M66 type can be applied not only an total condenser but also to partial
condenser.
