MoldMonitor pulsed-cooling temperature-control system consists of a single- or multiple-zone controller, heat sensor, and solenoid valves. Unit divides a mold into zones depending on the geometry of the mold and the distribution of heat load. It places a high-resolution thermistor sensor within 0.100 to 0.500 in. of the part surface to sense temperature increase as plastic enters the mold. The unit's microprocessor uses this information to start and stop a burst of cold water right after the mold has been filled. The pulse of water is triggered by the hot melt raising the cavity temperature near a thermistor beyond a threshold set for the type of plastic being molded. Timing of the pulse is based on the amount of BTUs to be removed from the part. The cooling pulse is never throttled. If more or less cooling is needed, MoldMonitor adjusts the length of the cooling pulse.

Temperature controllers available in water and hot-oil, open- and closed-loop configurations. Water units control to 250 F, oil-circulating units to 400 F. Space-efficient units have high-flow pumps, flanged heaters, and advanced electronic instrumentation with remote capabilities.

Portable chillers and chilling modules available in air- and water-condensed versions. Units from 1 to 30 tons with operating temperatures from 30 to 70 F. Chilling modules from 5 to 40 tons with operating temperatures from 20 to 60 F.

Pump-tank stations utilize minimum floor space while emphasizing vertical dimension for water storage. Standard process connections for pumps, sensors, drains, and water-level controls simplify installation.

Cooling towers in galvanized metal or fiberglass from 10 to 540 tons employ energy-efficient prop fans, generous wet decks, and large water reservoir.


Portable chillers in self-contained air- or water-cooled designs from 1/2 to 40 tons have accessible cabinet design, nonferrous water system, and microprocessor controls with dual-digital displays, lifetime warranty, seven positive-action switches, and 19 diagnostic lights.

Air-cooled central chillers include heat-reclaim indoor units or low-ambient outdoor units in capacities to 270 tons.

Water-cooled central chillers in two configurations: TSW economical plantwide systems from 20 to 90 tons with scroll compressors and two independent refrigeration circuits for precise control, and TXW dual circuit units with screw compressors from 80 to over 200 tons. All central chillers come with touchscreen panel with PLC and a three-year warranty.

Fiberglass cooling towers in FC and FT series from 15 to 240 tons. Units have a high-efficiency induced-draft design and strong, lightweight, noncorrosive FRP shell. Nonferrous construction and five-year total tower warranty (including motor) and 10-year shell warranty on FC series towers.

Pump/reservoir assemblies custom engineered in any size and configuration for tower or chiller applications. Have grooved pipe connection system; fiberglass, stainless-steel, or double-welded steel construction; solid pump decks; and premounted, prewired control panels.

Water-treatment systems control scale, corrosion, suspended solids, and microbiological growth with a single panel-mounted unit. Filtration equipment includes sand media filters, centrifugal separators, bag filters, and filter strainers.

Temperature-control units in a complete range of pumping, heating, and cooling configurations for oil and water from 0.75 to 7.5 hp, 3 to 60 kw. Utilized cast construction of twin tank and pump assembly. microprocessor with dual digital displays and five-year warranty, seven positive-action switches, and 15 diagnostic lights. Negative pressure units available.


Circulator line consists of temperature-control modules and bath vessels. More than 70 circulators, recirculators, and cryostats cover temperatures from -90[degrees]C to 300[degrees]C.


Water and hot-oil temperature controllers and portable chillers.

Water units in upright, low-profile, and subcompact configurations. Microprocessor controls have RS232C, RS422, and RS485 capability. Horizontal pumps with seal flush offer simple operation. Single- and multizone models with optional features.

Hot-oil systems control temperature from 100 to 550 F. Heater capacities from 6 kw and up. Centrifugal pumps incorporating water-cooled seals are standard. Upright and compact models available.

Portable chillers with air- and water-cooled condensing from 1 to 25 tons. Hot-gas bypass, stainless-steel or nonferrous fully insulated reservoir tanks, all-copper piping, and freeze-stat control.


Chil-Trak series reciprocating liquid chillers from 2 to 7.5 tons with remote condensers discharge heat outdoors and/or reclaim heat for use elsewhere. All sizes have Head Start receiver, which matches capacity with load to ensure smooth, consistent operation and low-ambient-temperature start-up. Front-panel access to valves for all sections of system.


Tempro line of hot-water temperature controllers in Plus and Basic models. Plus units have single or dual zones and come as either an open system with submersible pumps and no pump seals or as a pressurized system with magnetically coupled pumps. Pump capacity from 7.5 to 15 gal/min, and operating temperatures from 194 to 320 F. Heating capacity from 3 to 9 kw. Single-circuit Basic units operate up to 194 F or 284 F, depending on model. Can have a self-optimizing controller that monitors [+ or -] 1[degrees].
