Heat exchangers are used to transfer heat from one medium to another. They are a block with corrugated steel plates fixed in a special frame and pulled into a package. Heat transfer occurs due to the movement of fluids in countercurrent from the carrier to the heated medium. It is possible to buy a plate-type heat exchanger for both heating systems and hot water heating systems.
Heat exchangers for heating can perform the following functions:
- to separate coolants with different characteristics;
- provide protection against high temperatures;
- provide protection against high pressure;
- provide high-speed heating of water for domestic and industrial needs.
In the online store site in Cheboksary, you can pick up heat exchangers for heating, ventilation, cooling, antifreeze heating, path heating and industrial applications. Thermal power (kW) and maximum working pressure (bar) directly affect the price of the equipment.
Heat exchanger Mashimpeks model NT 100 T- collapsible type lamellar apparatus. It is effectively used in housing and communal, as well as in energy, food, petrochemical and other industries. Operating since 1997 and occupying one of the leading positions in the market of engineering equipment, Mashimpeks regularly upgrades the produced heat exchangers.
The NT 100 T plates are designed in such a way that flows are evenly distributed over their surface. A small area of the plates as a result gives a large heat transfer. Increasing efficiency saves money.
Benefits of Varitherm NT 100 T
automatic alignment and self-positioning of a set of plates;
more reliable optimal fixation of non-adhesive seals using ECO-LOC technologies (NT series), ensuring complete tightness;
optimized configuration of the profile and corrugations of the plates.
This simplifies the maintenance of the heat exchanger, eliminating the possibility of incorrect assembly of the plates. In addition, Mashimpeks heat exchangers have the effect of self-cleaning from scale, which is provided by high flow turbulence. In general, the correct installation, use and care of a gasketed plate heat exchanger allows you to use it without problems for at least 15 years.

Seal characteristics
Gaskets for GEA NT100 plate heat exchangers are gaskets made of various materials with several modifications.
Prices are indicated in rubles, including VAT
The most common GEA NT100 seal materials are:
EPDM(abbreviated from ethylene propylene diene monomer) - EPDM ethylene-propylene rubber that can withstand heat exchanger operation at coolant temperatures up to +150 ... +160 0 С. EPDM material is suitable for operation of the GEA NT100 heat exchanger with steam and water without oily inclusions.
NBR(abbreviated from nitrile Buna-N rubber) - butadiene acrylic-nitrile rubber with a maximum operating temperature of the coolant +120 0 C. The NBR material is suitable for the operation of the GEA NT100 heat exchanger with steam, water, mineral and vegetable oils.
NBRP(abbreviated from nitrile Buna-N rubber peroxide) - improved butadiene acrylic-nitrile rubber with a maximum operating temperature of the coolant of +130 0 C due to the addition of components to the feedstock that increase the operating temperature of the seal. NBRP is also suitable as NBR for the operation of the GEA NT100 heat exchanger with steam, water, mineral and vegetable oils.
GEA NT100 special seal materials:
HNBR(abbreviated from hydrigintated nitrile Buna-N rubber) - butadiene acrylic-nitrile hydrogenated rubber with a maximum operating temperature of the coolant of +145 0 C. The HNBR material is suitable for the operation of the GEA NT100 heat exchanger with mineral and vegetable oils. It is especially often used in steam-oil heat exchangers, in which the operating mode allows the temperature to exceed up to +145 0 С (for a short time up to 155 0 С).
VITON-STEAM®- (steam VITON). Also known as a type of FPM fluorine rubber. The material belongs to the group of special temperature-resistant materials and is intended for plate heat exchangers GEA NT100, in which steam with an operating temperature of up to +200 0 C is used as a heat carrier. water.
FPM-G (VITON-G®)– a variety of VITON material for use on GEA NT100 steam-oil heat exchangers.
Note: VITON® is a registered trademark of DuPont.
BUTYL-HT(butyl) is a special chemically resistant material, heat exchangers with seals made of which are intended in particular for heating alcohol and alcohol-containing media, since conventional materials (eg EPDM) cannot withstand contact with alcohol.
HYPALON, SYLICON, NEOPREN– special chemically resistant GEA NT100 seal materials for highly specific applications.

Gasketed plate heat exchangers varitherm GEA Mashimpeks
VARITHERM plates (VT series) are the traditional and most commonly used plates in the production of heat exchangers. The VT series is represented by 23 types of Varitherm plates. They come in different sizes, corrugation profiles and match different heat transfer and pressure losses. Heat transfer surfaces from 0.05 to 2.5 sq. m per plate and up to 2000 sq.m per plate package.
The capacity of plate heat exchangers of the Varitherm series can reach 3600 m3/h.
VT series (Varitherm)
Package may consist of plates of one or more profiles. In the package, each subsequent plate is turned 180 degrees, touching so that channels are formed between the plates. If plates with different profiles are used in the same plate package, several types of channel geometries can be created. Different angles of the plate profile provide different thermal characteristics, pressure losses. No more than two types of plates can be used in one package. The ratio of these types of plates is chosen in such a way as to fully correspond to the desired operating modes with minimal pressure loss. |

Due to the wide variety of plates, plate heat exchangers are used in many industries:
NT-series
Gasketed plate heat exchangers NT GEA Mashimpeks
Improved performance, wider range of applications, ease of maintenance at minimal cost - all these are NT series plate heat exchangers.
The optimized configuration of the profile and corrugations of the plates allows you to achieve more heat transfer power with a smaller heat transfer area due to a more uniform distribution of flows over the entire width of the plate. Naturally, this significantly reduces the cost of the new heat exchangers of the NT series.
The NT plate series expands the scope of heat exchangers. A wide variety of plates allows more flexible and efficient use of plate heat exchangers in various technological processes.
The use of a new type of seal retention and a new special plate design simplifies and speeds up maintenance, as well as guarantees accurate seal retention and self-positioning of the plate pack.
A wide range of NT series plate sizes and profiles ensures optimal heat transfer and minimum pressure loss in NT series heat exchangers
