Standard gasketed material

  • NITRIL
  • NITRIL PEROXIDE
  • EPDM
  • EPDM PEROXIDE
  • FPM
  • PTFE

Gaskets type
LOCK SYSTEM GLUELESS (clip)

STANDARD PLATES RANGE
Connections from DN25 up to DN500 Standard connections:

threaded external or internal UNI and/or BSP, flanged UNI, ANSI, SAE TRICLAMP, for food and diary or pharmaceutical applications

Pressure range from PN6 up to PN25, full vacuum.

Heat recovery from steam

03/11/2015

In turbine power generation unit, big shell and tube heat exchangers are installed to condensate and cool down the steam. Due to design conditions, this kind of heat exchangers is a must…but…

You can achieve interesting energy recovery, on low temperature steam with plate heat exchangers.

The new improved DN300 and DN500 plates give us the chance to install some big units to get this results:

  • DN300 plate type TCP9A – 15MW
  • DN500 plate type TCPZZ – 25MW

Both installed to produce hot water for heat district units, from low pressure steam (4 barg).

Customer installed 2 big plate heat exchanger for 150% total capacity, in this way they can get 75% of power also in case of unscheduled maintenance.

Vent condenser

27/10/2015

Chemical reactor vent condenser are usually made with shell and tube heat exchangers.

In Tempco from many years we suggest a better solution with plate heat exchangers.

There are mainly 2 solutions:

We employ welded or brazed ones, because these applications needs perfect sealing to pressure and to full vacuum conditions.

The brazed ones are usually full inox esecution and semi-welded have PTFE gasket. both solutions are suitable with corrosion proof requested from chemical fluid.

Rubber and thermoregulation

12/10/2015

After summer holidays, we come back and start-up two new interesting thermoregulating plant, both installed on rubber production machinery.

The two units replace old steam heating plant and both are designed to work witj diathermic oil at 265°C max.

 

Customer needs to regulate the temperature of different worktops with different set-point, due to changing rubber mix from floor to floor.

After a careful check of different solutions, we opted for a “smart” solution, which provides a single heating unit, with the possibility to modulate the power, with a series of devices for adjusting the temperature of the different plates of the press.

The result is extremely functional and efficient, put the customer in a position to start the budget to convert suits presses of establishment of this new system of thermoregulation.

Worry?…better prepare

12/06/2015

Summer is coming, hot is arrived!

A lot of our customers are prepared:

  • They have replaced the filling of the evaporation towers
  • They installed systems adiabatic retro-fit on the dry cooler
  • They have made maintenance to the plate heat exchangers

Their production now go at the best.

Who did not do it now cares, what can you do?

Contact our service, which is prepared on time, we have in stock ready to stock, spare parts, seals, packs filling, ready to be delivered and installed and to be prepared and not worried.

TCOIL unconventional thermal energy

09/06/2015

TCOIL immersion heat exchangers are very flexible and suitable for a wide range of thermal energy management applications.

Heat pump linked to low thermal energy source is one of the interesting application of TCOIL.

The extreme tailor-made feature of TCOIL dimple jacket heat exchangers, make them easy to use on textile, steel mill, paper mill, chemical  and other low temperature energy recovery applications.

Maintenance operation are very easy and cost saving. It is possible to supply TCOIL electro-polished, to avoid scaling and achieve an extra easy cleaning.

Slurry Ice, green cooling innovation

28/05/2015

Slurry ice is a curious expression, lately emerging in industrial cooling applications, freezing and conditioning: it consists of a natural refrigerant, a sort of mud made by water and small ice crystals in suspension.

It is employed as a biphasic cold-vector fluid (liquid-solid) offering high thermal transfer efficiency due to the highest surface area available thanks to the suspended ice crystals, turning it into an innovative kind of fluid refrigerant. Slurry ice has increasingly several applications in process industry cooling, in sectors such as food & beverage, construction industry and medical, combining energy efficiency and lowered operative costs.

Metal corrosion in thermal machines

24/04/2015

Selecting a heat exchanger, and in general a thermal machine, the right selection of construction metals is fundamental, in order for metals to be suitable for the kind of application and effective working conditions of the machine.

Corrosion is in particular a major topic, to be carefully considered since the engineering design step, for an equipment or a customer’s plant. Metals are indeed exposed to several external agents, being subject to natural deterioration. Entity and type of factors that can contribute in several and different ways to the corrosion of a metal must be clearly evaluated, in order not only to choose the right material, but also to calculate the right thickness for the components.

Here is also a very useful and comprehensive guide on corrosion on metals, going in depth on the range of anti-corrosion coatings, inhibitors and pigments.

Adjusting the temperature in the paper mills processes

17/04/2015

The production of paper requires heating and cooling processes during the various processing phases.

Paper mills normally have sizeable heating systems, often combined with cogeneration plants, that maximise the huge amount of thermal energy produced and used, recovering energy from waste production.

Some processing steps involve a precise control over the temperature, requiring specific high-precision systems because traditional steam systems cannot always meet this requirement.
