In the manufacture of injection

molded parts, correct mold

temperatures can reduce reject rates

by 24% and improve productivity by

up to 20% (Research

report by the Aachen Technical

University/Germany).

Temperature control of injection molds, extruders,

rollers, vessels, and other applications.

Additional advantages:

Minimal reject rates beginning at production

start-up. Better cavity-filling performance. Closer

tolerances. Minimizes warping and shrinkage. Better

surface finish. Continuous high-quality production.

Temperature control units for water up to 195°F or

thermal oil up to 300°F

The RT50 control system ensures an optimal fit for

practically every application. The RT60 control system

and the RT32 controller are a simple, cost-effective

solutions for a wide variety of applications.

All controllers are designed to avoid problems before

they arise.

Modern automated manu-

facturing processes require

data transfer between the

temperature control unit

and the production facility’s

central computer – just one

of many applications for

the RT50 and RT60 control

system with data interface.

REG descaling unit and descaling agent REM93,

corrosion inhibitor RK93 and system cleaner SR80

With the REG descaling unit, descaling agent REM93 for

water and steam systems, corrosion inhibitor RK93 and

system cleaner SR80 for oil circuits, Regloplas offers their

cus tomers optimal assistance for maintenance.

Descaling unit REG and descaling

agent REM93 for cleaning

of molds and dies, cooling

circuits and other systems

operated with water or steam.

Corrosion inhibitor RK93 prevents

corrosion, lime deposits and the

formation of rust in water circuits.

System cleaner SR80 is a highly

effective additive for cleaning heat

transfer systems and other circuits

contaminated by oil residue.

• Incorporated heating ➔ Minimal cleaningtime.

• Simple connection to the encrusted circuitwithout dismantling of the installation ➔ Operation without problems, time saving.

REM93 Descaling agent

• Environmentally friendly and biodegradable.

• The combination of an organic acid with aninorganic activator results in a descalingagent that has the same effect as a strongacid: quickly and efficiently removes lime,scale, and rust deposits without damagingthe equipment.

• Also suitable for tin and enamel.

• 1 kg REM93 removes approx. 1 lb of lime.

At the Regloplas Test Center, any operating

condition can be simulated and checked—

under continuous testing.

• Electric control in separate housing, heaterprotected against running dry, tank of plasticand cover of stainless steel ➔ Safe and effi-cient operation.

System cleaner SR80

• The additive removes oil-carbon residues andforeign contamination from metal sur faces.They circulate in the oil flow and are carriedto the filter.

• The optimal cleaning effect is between 250 and 300 °F.

• The max. permissible operating temperatureis 570 °F.

• The SR80 additive contains no solvents.It can be dissolved in all mineral oils andsynthetic fluids.

• Application as a preventive or beforechang ing the oil.

Corrosion inhibitor RK93

• Temperature range 15 to 355 °F.

• The additive helps prevent: electrolytic corrosion of all metals, dezincificationof brass, lime deposits and adherenceof hard rust particles.

• RK93 can be mixed with GLYCOL productsand does not attack seals.

• Suitable for pressurized water systems.

• Economical to use.

• RK93 retains its properties over an extendedperiod and forms a protective film on thecontact surfaces, providing constant effi-ciency of the heat exchanger.

Notes

Expansion of the heat transfer fluid

The value given in the table “Technical Data”must be higher than the volume increase dueto temperature during operation.When the installation is idle, some of the con-tents of the consumer may flow back to thecontrol unit, depending on the set-up (differ-ence in level between temperature control unitand consumer). In large-capacity consumers(e.g. rollers), the value specified ensures thatthe heat transfer fluid flowing back to the con-trol unit can be accomodated.

Cooling capacity

Generally speaking knowing the maximumvalue alone is not enough to determine thecapacity. We provide a diagram of the coolingcapacity.

Pump capacity

Knowing the maximum values alone is notenough to determine the pump capacity. Weprovide the characteristic curve of the pump.

Control

Control accuracy. Short-therm accuracy of thetemperature control circuit (controlled system)is very difficult to pinpoint. The accuracy of theRT50/RT60 control system and the RT32 con-troller alone is better than ±1.8 °F.

The accuracy of the temperature control circuitcan vary considerably, depending on thestrength and duration of the disturbances affect-ing the circuit.For example:– Production start-up– Production interruption– Changes in the injection cycle (injection

molding)– Changes in the material and ambient tem -

perature.Cascade control: If the consumer is equippedwith a sensor, the control system automaticallyswitches to cascade control: Using two cou-pled controllers, the temperature of both thefluid and consumer is controlled. Cascade con-trol enables optimal control of the consumertemp erature, a critical factor in overall produc-tion quality.

Unit selection

Minimum data required:1. Set value temperature/temperature range of

the consumer.2. Weight or dimensions and material of the

consumer.3. Desired heat-up time in hours.4. Quantity of processed material in lb/h

and designation of the material.5. Temperature of the material to be process -

ed when it reaches the consumer (e.g.injection mold).

6. Max. cooling water temperature (if >65 °F).

InterpretingRegloplas data

The following notes provide important information on

interpreting the technical data and selecting Regloplas

temperature control units.

22

Since there is very little systematically compiled,

technically relevant documentation on temperature

control, we have provided it ourselves.

Regloplas’ technical

literature: Our books,

Temperature Control

by Means of Fluid

Media, and

Temperature Tables, are

valuable tools for day-

to-day practice.

It’s obvious that optimizing quality

and productivity also has a positive

effect on the environment. We see

this as an opportunity to improve

our own production continually,

as well as to design our tempera -

ture control units to maximize both

performance and conservation of

resources.
