Q:
What new technologies are influencing terminal block design?
7 answers
Answers:
Several - the Fluid and the material the chuck or block is made of are important and changing all the time. Also, direct expansion has proven the best.

The individual terminal block manufacturers isn't something I am an expert on. I also use the term Block or chuck but I think you may be thinking the CPU cooling? I have worked with IBM, AMD, DELL, Delta Design and other on Chip cooling applications.

Applications and UseTop

Q:
Please share with us any “non-standard” applications that terminal blocks have been used for.
5 answers
Answers:
Cooling of big wine storage warehouse,normally did it with close control units. In this case I did with a chiller with a micro pulverization system. More efficient, more cheap, more low maintenance costs... one more costumer satisfied!
~José Gonçalves, Engineering Consultant, Lisbon, PORTUGAL
Semiconductor chip cooling in many applications from CPU to the front and back end of the manufacturing process of an IC. Also cold plates are everywhere.
~Kyle F, Technical sales engineer- Thermal solutions, Wolfeboro, NH
Solar thermal for heating and cooling.
~Wladyslaw S, Builder/Contractor, Elmwood Park, IL
Still trying to find some
~Ravi S, Research & Development, Greater noida, India
Rings

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of terminal blocks?
3 answers
Answers:
Don`t have water filters on the installations. Make the installations near the see without any additional treatment(blue fin, gold fin....) at least on the coils.
~José Gonçalves, Engineering Consultant, Lisbon, PORTUGAL
Overheating and short circuiting the block.
~Nazario S, Technical Support, Safat, Kuwait
Burn outs due to incorrect sizing.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
8 answers
Answers:
For the coast market, chillers with the exchanging in the sea water. I've made a few with external heat exchangers and they are working very well. If is included in the units it will be a fantastic package. Heat recovery is crucial.
~José Gonçalves, Engineering Consultant, Lisbon, PORTUGAL
Larger surface area of frame base to improve stability when rolling units. This would also assist in better placement of jacking equipment during installation and removal procedures.
~Bruce J, Industrial Moving Supervisor, Abbotsford, Canada
Understanding the max flow and amount of heat to withdraw.
~Kyle F, Technical sales engineer- Thermal solutions, Wolfeboro, NH
Chiller that does not use electricity..
~Ravi S, Research & Development, Greater noida, India
Better efficiency at max capacity.
~Engineering, Consulting, Cooks Hill, Australia
Simplified controls.
~Engineering, Other, Belo Horizonte, Brazil
More user friendly.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using terminal blocks?
3 answers
Answers:
1)Confirming that the characteristics are certified. 2)Check the efficiency( ESEER). 3)Check the sales and after sales guarantee.
~José Gonçalves, Engineering Consultant, Lisbon, PORTUGAL
Should take into consideration the temperature and short circuit current
~Nazario S, Technical Support, Safat, Kuwait
Look at the VRV system
~Colin C, Technical Support, East London, South Africa

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of terminal blocks?
3 answers
Answers:
Select the units for the most correct temperatures of the most probably functioning time. Be aware of the correct designated function of the unit. Be informed how to use it with your supplier .Have a good preventive maintenance.
~José Gonçalves, Engineering Consultant, Lisbon, PORTUGAL
Look at the brand before making your selection.
~Colin C, Technical Support, East London, South Africa
Using under rated blocks.
