Flexible brazed plate heat exchangers

26/09/2013

Plate heat exchangers are suitable for multipurpose use, due to their flexibility

The great turbulence inside the channels get maximum perfermance and thermal coefficients.

Sometimes we need to break this power:

  • viscous fluids
  • high flow rate
  • low pressure drop

We can achieve different thermal duty, simply changing the chevron angle of plate corrugation.

Now the TCB2100 get the same flexibility, choosing the H, M, L corrugation, in order to achieve the best performance and the best pressure drop.

With new TCB2100 design, you can manage at the best:

  • different flow rate from primary and secondary
  • low pressure drop
  • high thermal coefficient

 

 

TCB2100HML

 

TCB2100 is the solution for:

  • hydraulic
  • lubrication
  • HVAC refrigeration
  • steam heating

TFIN IDRY adiabatic dry cooler

16/09/2013

We spoke about these dry coolers few time ago.

Anyway our technical department records an increasing of these request and installation.

In 2012 we install little quantity of TFIN IDRY, but in 2013 first 6 months the 40% of the dry-cooler was equipped with IDRY module adiabatic system

 

TFIN IDRY adiabatic system

 

On january 2013, we work hard on a new software, focused to calculate the waste-water and energy saving on TFIN IDRY system.

Soldering connections on brazed plate heat exchanger: how to do

06/08/2013

When you need to sold a brazed plate heat exchanger on copper pipes, you need to follow few clear instructions.

scambiatori a piastre ad elevata efficienza

To avoid damage to heat exchanger, please remember to check following points:

The connection of brazed plate heat exchanger is stainless steel, thus, it is necessary to use high containing silver solder to solder with (castolin for instance).

Please follow the guides below:
1.Before starting soldering, the copper pipe and the connections should be perfectly cleaned.
2.During the soldering process, applying soldering flux is recommended in order to protect the pipe and heat exchanger from oxidizing and also help cool down the temperature.
3.The brazed plate heat exchanger should be placed in a horizontal position during the entire process, and place wet cloth around the connection base to protect the heat from conducting to the plates.
4.Silver solder containing at least 45% of silver should be used for soldering. The soldering temperature must not exceed 800°C.
5.When the soldering temperature is too high or the duration is too long, potential consequences include the melting of brazing points or damage of the plates which will cause leakages.

Biogas condensate, separator or tank

04/07/2013

We have now installed several tens of  biogas dehumidification systems, and we are proud of them, in fact they are all functioning and have received positive feedback.

From the beginning when dealing with the design for this application, we did it with our staff linked to the world of the process:

  • efficiency
  • efficacy
  • reliability
  • simplicity

Lately we are seeing some applications that leave us perplexed, I speak mainly of the final part of the system, i.e. the one linked to the condensate.

Our system is very simple and consists of:

  • refrigeration unit
  • heat exchanger/dehumidifier
  • condensate separator/trap

Abandonment of gas R22 refrigerant

29/05/2013

R-22 PHASE OUT

Programming of the abandonment of gas R22 refrigerant:

From 01/01/2010:

• It is not longer possible to produce and export machines with R-22 (for the European market the ban dates back to 2001)
• It is no longer possible to use the gas R-22 “virgin” for top-up or replacement during maintenance operations.
Replace your old refrigerator R22 and save 25%
A modern chiller with scroll compressor and R410A gas consumes 25% less than an old R22 chiller with reciprocating compressors.

Let’s take an example of how much you can save by replacing an old refrigerator power rating 70,000 kcal/h, assuming an age of 10 years, a natural drop in performance over time of evaporator and condenser, R22 and reciprocating compressors.

Old refrigerator consumption: 172,763 kWh / year
Coefficient of refrigeration old refrigerator consumption: 4,13
Last generation Tempco refrigerator consumption: 128.631 kWh/year
Coefficient of last generation Tempco refrigeration: 5,52
Saving 25%
= 44.132 kWh/year at medium cost of 0,15 Euro/kWh
= 6.619,00 Euro/year
If the same is associated with a free cooling system, the savings can exceed to 80%.

Chiller and Service

09/05/2013

On summer season, industrial plants gives problems related to hot ambient temperature.

Last week our service receive a call related to a big plant which don’t perform at usual temperature.

Customer tell us that chiller can’t perform correct temperature during middle day.
