Biogas condensate, separator or tank

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

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

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.

Immersed coils or TCOIL plates

On our italian blog we often spoke about the flexibility of TCOIL heat exchangers.

I’m firmly believe in this product and every time we get feedback from market of this feature.

Few weeks ago our good customer operating in steel mill field, contact our technical department because a coil heat exchanger, internal to a waste water single effect evaporator is damaged; the coil has some pitting, but more important is totally scaled and externally clogged.

Energy recovery from air compressor

Air compression central station needs big amount of energy to run.

Compressor generates heat which usually can’t be recovered, but must be dissipated with heat exchanger, evaporative cooler or dry-cooler.

This thermal energy can’t be recovered because the temperature are too low.

There is a fluid inside compressors which operate at higher temperature, it is our target in energy recovery: lubricant oil.

TREG HCE tires and thermoregulating units

Thermoregulating units TREG HCE are often employed on rubber industry, to heat up or thermoregulate production cycles.

In the last weeks of 2012 we close a supply for a new plant od high performance tires, where ours TREG HCE are dedicated to thermoregulation of cord production lines.
