Heating in poultry industry

An interesting application of dimple jacket TCOIL plates is really also a basic one, consisting of heating and maintaining the right temperature in a water tank.

Being curious and of interest is instead the specific contest of use, as we are talking about plants for poultry and food industry products preparation, which have to be pre-heated at a certain temperature in order to achieve the most suitable processing conditions.

Long plates for anodic oxidation

Revamping and rebuild intervention for the substitution of old heat exchangers, impossible to recover, installed in anodic oxidation plants.

We already covered the topic of anodic oxidation a few months ago, talking about aluminium where the treatment process is employed to increase corrosion resistance of the material, for harsh environments applications.

The process consists in the use a galvanic bath, with a solution of water and sulphuric acid, and the passage of low voltage current.

Semiconductors cooling unit at CERN

Tempco provided the CERN in Geneva a cooling unit system for deionized water to be supplied to IGBT testing equipments. The IGBT are insulated-gate bipolar transistors, three-terminal power semiconductor devices primarily employed in high power applications, mounted on NPC converters (Neutral Point Clamped).

The testing platform required is used in the CERN Technology department dedicated to EPC and PHC, Electric power converters and High power converters. The aim of the testing platform was to test damaged components after reparation before they are put back into operation in NPC power stacks converters. The Power stacks tester comprises two DC sources connected in series, with a cooling unit to provide the necessary water flow to cool the power stacks.

Cloud computing discovered… warm water!

In The Netherlands is it possible to heat water with a computer. Well, let’s better explain it, heating water using the waste heat from servers. We’ve talked about it already in a previous article a few weeks ago, and we are pleased to go more in depth in this interesting project: the innovative idea comes from the start up Nerdalize, and consists in the recovery of the waste heat produced by a distributed network of servers, installed at homes, employed to produce hot tap water. Servers in traditional datacenters consume a lot of energy and produce a lot of waste heat, requiring the 40% of the electricity consumed for server’s cooling.

The Nerdalize solution optimizes in a smart way the energy consumption, and the company built its own heating device that integrates the computer servers in it, able to manage the heat exchange from the servers to hot water. The system is called CloudBox and comes with a boiler tank, and is an add-on easy to install in existing central heating systems. Installation is handled by the company, which also pays the energy used by the servers.

Temperature regulation on Steel mill fournace gases

Modern production technologies in the metallurgical field of application, require the employ of particular gases such as argon.

The need is to obtaining stable and defined crystalline structures, so that the end product achieves the expected mechanical and physical characteristics.

The development of these technologies continues and even a correct and predetermined thermal level influences the achievement of the required result.

As a consequence of this, we realize systems that use the brazed plate heat exchangers, combined with thermoregulation units, to thermoregulate the gas that is injected in the metallurgical production fournace.

Shell and tube heat exchangers, special execution for pharmaceutical industries

We discuss very often about plate heat exchangers, but less about shell and tube heat exchangers. Let’s cover the gap and let’s talk about special shell and tube heat exchangers that we realize in Tempco for pharmaceutical industries, especially engineered to provide the production process with hot water from low pressure steam.

This kind of shell and tube heat exchangers for the pharma sector have special full stainless steel execution, meeting the hygienic requirements of the sector and to prevent possible corrosion in contact with aggressive substances.

The 5 must to-do point to start-up TREG HCE/HCST O/OH diathermic oil

1. Check safety and control devices: for correct installation and functioning, be sure that the range settings are proper for the operation. Manually activate and test the instruments and apply all tests necessary to assure the right functioning.
2. Check for leakage.

3. Remove moisture from the system, using dry compressed air or other suitable means.
4. Fill the system with heat transfer fluid.
Fill the system with heat transfer fluid, with all vents to the expansion tank or atmosphere open for air removal. Fill the expansion tank to low level. Where needed (in low temperature environment), have the steam tracing system switched on.
Open all valves, then start the main circulating pump in accordance with the manufacturer’s recommendations. Observe the liquid level in the expansion tank, refilling as necessary until the system has been filled. The expansion tank should be adjusted to 70%–75% full when the hot operating temperature is reached.
Suggested start-up procedure for new systems circulate the heat transfer fluid through the system for about 4 hours to eliminate air pockets and to assure complete system fill. Before firing the heater, be sure that the heat transfer fluid is circulating freely through the entire system.

5. Start the heater. Bring the system up to temperature very slowly—about 35°C per hour. This should prevent thermal shock to heater tubes, tube/heater joints, refractory materials, etc., and will allow operators to check the functioning of instruments and controls. The slow heat-up also will allow moisture trapped in all sections of the system to escape as a vapor.Hold the temperature above 100°C until no signs of moisture remain (e.g., knocking or rattling of pipes, moisture from vents, etc.).

Merry Christmas… and Smart Heat recovery from Tempco!

This year, in Tempco we want to wish you a warm Merry Christmas in an even smarter way…
An interesting tip related to heat recovery and datacenters comes indeed from Nerdalize, a Netherlands based company. The idea is to combine the growing demand of computing power with the heating need in homes, leveraging on a delocalized network of cloud servers in homes.

Tempco Auguri 2017 Nerdalize cloud server recupero calore

The solution could be an alternative to traditional big datacenters, huge energy wasters that employ 40% of its total energy consumption on cooling and dissipating the heat produced by servers.

Cloud servers at homes would then represent a sustainable computing power source and an immediate source of heating power, decreasing at once both energy consumption aimed at datacenters’ cooling and households’ energy bills, thanks to heat recovery from servers directly in homes.

And with that in mind, the Tempco team would like to wish you a very Warm and Merry Christmas, and our most sincere wishes for a Happy New Year 2018!
