Love them big block chevrolets!

[frank shelley]

At least for me doing residential and Lt commercial, big pretty stuff like that gets me excited.

[edrock]

I have VERY little Chiller experience,But I have a question.Why gas and Not diesel engines?Iwould think diesel would be best for this..

[pmccune]

Because Natural gas burns much cleaner than diesel fuel. But we do have big Catepillar and Waukesha engines on our 600 to 1000 ton chillers. Also the 454 is a tough engine this motor is basically a boat engine with the water cooled manifolds, it is almost bullet proof.

[edrock]

thanks for reply.was just wondering

ooooh, geeee wiz! I see big industrial stuff like this and my blood starts to flow down stairs. My question is what is it cooling? Plus what is in the 2 55gal drums?
The biggest I have worked on was 200 and 250 ton chillers that used r-114. 2 of them on line at the same time will keep the ship and all the eletronics cool.

[Diceman]

How many miles does it get to the gallon too?

[pmccune]

This a chiller 400 ton used at a hospital for cooling regular chilled water loop. Also those ar crusader.

[hw chiller man]

The big drums are motor oil which is continually pumped into the motor crankcase when the compressor is running. The overflow from the crankcase then drains back into the drums. This increases the time between oil changes for the motor. These chillers are pretty slick and also provide a good supply of hot water if a large domestic load or other heating load is available. They are high maintenance items pmccune.

[pmccune]

Yeah they sure are I work on them every day. But when they run they do a good job. That is a baby compared to the 1000 ton I have in Raleigh NC.

[hw chiller man]

I service one also, with the Howden compressor and the same engine as you have there. 150 tons I believe, approx 10 years old, one of the first in Canada, the largest that Tecochill made at that time. Do you guys do the repairs to the motor, timing, valves heads etc. or just stick to the refrigeration side. We had a valve job done on ours two years ago, this thing runs great. Only major problem occured in an thunderstorm when all the boards were fried, major dollars.

Hello Chiller Man,

Yes we take care of all areas of the tecochill, tecofrost, and cogeneration. I only work on the chillers but I take care of the engines and refer side, I did HVAC wor before I knew anything about motors, and I also take care of two howdens have one with 48000 hours on it in VA. What area are you in.

[hw chiller man]

I am located in Windsor Ontario, across the river from Detroit. The chiller I referred to is used in a demo site with a 19DK Carrier centrifugal chiller. The two are piped in parallel and are data logged continually to find out which is more economical to operate. I beleieve with our lower hydro rates that the centrifugal is more economical but I understand that there are a ton of these chillers in Texas where hydro is more expensive. My particular chiller has no use for the high water temps so that heat is rejected to the tower and they realize no savings there. My chiller ic also R22.......regards

[pmccune]

I have a site that they just set a 2000 twin centrifugal trane thats is a monster. Our new tecochill uses 134-a and is 30% more efficient. Very reliable too. Take Care

[themadwirer]

get some pics of that 2000 trane unit put them up on here.

Will Do
