water & oil temperature control: whether your molds run cold or hot, new chillers, tcus, and cooling towers can save you energy, floor space, and maintenance costs. some of them even talk to you over the web.
If you need such peace of mind, you can get it from the \"network\"
Enabled the \"mold temperature control unit\" (TCUs) launched at the large NPE exhibition in Chicago ).
Monitoring aids in cyberspace may make some of you feel a little strange, but most of the new developments in fluid temperature control in NPE are very pragmatic.
The news is mainly on components that are more compact, durable, less prone to leakage or corrosion, able to heat or cool the mold with less energy.
More security features and easierto-
Use controls are also common on new coolers, towers, pump tanks and TCUs.
In many cases, the cost of these features is the same or lower as the previous model.
The new portable chiller Budzar Industries has upgraded the portable chiller with PLC and touch screen to display complete operating conditions, diagnostics and trouble shooting guidelines when required.

2 to 15 tons of cooling models are now all
Stainless steel cabinets, non-ferrous metal pipes, copper welding
Plate heat exchanger and rolling compressor.
The new central chiller of central chiller employ uses a rotary compressor, which is said to be more reliable and efficient than a reciprocating compressor (discus)compressors.
The latter has twice as many moving parts, resulting in more noise and vibration.
The R series consists of two sets: RC models of 30 to 100 tons with rolling compressors and stainless steel brazing-
RS units using screw compressors are 60 to 195 tons (
Say more efficient)and shell-and-
Tube evaporator of more than 100 tons;
The smaller units in this group have a more compact stainless steel brazing-
Although the RC model uses the traditional R-
22 refrigerant, RS model use updated R-134a non-
CFC refrigerant with less ozone
Energy consumption has also increased by 12%, according to AEC.
Although R134a has been used by small chillers, the AEC considers its RS model to be the first large industrial screw-
Type unit using this refrigerant.
Two levels of Allen
Bradley touch screen control available in the R series--
A basic monochrome version that can control up to four compressors in one or two circuits, as well as more advanced color models for cooling
Tower Fan and water pump, and chemical water-Handle the pump.
Sister company Sterlco has introduced similar S-Series central chillers, except that Sterlco uses Mitsubishi\'s plc instead of Allen-Bradley.
Berg Chilling Systems has a new production line for large packaged chillers and pumps of 30 to 200 tons.
Since they are all built on one level, they have a smaller footprint and easier service.
They have a new, simple one. to-

New WM of Budzar (water-cooled)and AMO (outdoor air-cooled)
The central chiller has a PLC and touch screen that displays a complete guide to operating conditions, diagnostics, and trouble shooting.
The company said that remote diagnostics can be done through a modem, and the software will continuously adjust the chiller according to operating and environmental conditions, thus reducing the operating cost/ton.
The two series range from 20 tons to 400 tons.
AMO series available in split system or optional on-board pump-

Standard features all-
Stainless steel structure and electronic heatgas bypass--
It is said to be more accurate than mechanical bypass.
The new cooler product from Regloplas will include a central model of up to 150 tons.
Care has upgraded its TX series central chiller with a screw compressor up to 440 tons.
The company now offers compressors of 70 to 220 hp, compared to the previous maximum pressure of 60 hp.
The upgrade allows the use of a large compressor instead of two small compressors to reduce costs and the floor space of the machine. (
On the other hand, double compressors provide redundancy and better efficiency at low loads. )
It is said that the electronic expansion valve is also new and can improve energy efficiency under reduced head pressure.
Over the past year, Care has also introduced color touch screen PLC controls for its central chiller.
It shows the cooling system and operation of the whole plant
Hours on all devices.
You just touch an icon to display all the details of any device in the system.
In addition, the Care TS Series central chillers up to 100 tons have a new lowcost Allen-
Bradley PLC and PanelView display.
The mighty redesign of its central unit was collected from the parliament building Temptrol.
Models up to 300 tons can have screw, reel or discus compressor.

The circuit system can have such
The coil packaged with the cooler is called \"Free Cooling.
This allows the system to automatically switch from the cooler to ambient cooling whenever the outdoor temperature drops to 40f or lower.
Some companies have also introduced new pump tanks for the central cooling system.
Mokon, for example, introduced the first line of its products of this type, with a standard size of 250 to 3500 gal, stainless steel or carbon steel.
Middle Size added to hot care-1100 gal--
Its fiberglass/plastic pump tank series, up to 2200 gallons.
There are also new compact lines (1/16 DIN)control.
Vitman introduced an unusual pump.
Tank design for four pumps at the same price as the usual three.
The standard system has a re-circulating pump, a process pump, and usually a spare pump that can replace either of the first two.
On the contrary, Wittman\'s new setup has two pairs of Armstrong pairsarm pumps--
Recycling pair and process pair.
One member of each pair is behind-
It will start automatically if the first one fails-
Or these two pumps can be used alternately to minimize wear and extend life.
These Armstrong pumps use integral valves to reduce costs.
Wittmann says they also don\'t need bearings for their vertical installation, so it\'s quieter to run.
It is said that the oversized accessories provide 60% more traffic than the typical system.
The pump tank is also part of the new cooling unit
L-system productsR Systems.
They range from 250 to 5000 gallons and pump 2 to 60 hp.
New controls for smarter cooling tower cooling towers and pumps
The superior project highlights the storage tank station.
It is said that the new checkmate series is cheaper and simpler to use than plc and can control up to 12 motors.
Two versions are available: the LE model has an LCD display and the HE version has a touch screen.
LE shows the water temperature in and out of the process, allowing you to change the thermostat settings without opening the cabinet.
He can show the time/temperature chart and the operation of the fan-time hours.
Options include displaying water quality--
PH and dissolved solids-as well as wet-

Vitman claims to have launched the industry\'s first \"web-enabled\" TCUs.
They embed a web server in the control, allowing users to access set values, maintain documents, operation instructions, and troubleshoot help from anywhere.
The Web server also has an interface with Wittlink software from Wittmann, which \"allows the set-point and Operation Data to communicate with the entire unit of the Wittmann auxiliary device.
