4.4 Fluid considerations

IntroductionThis section outlines the fluid considerations for MultiTemp IV Thermostatic Circulator.

WARNINGFlammable liquids. MultiTemp IV Thermostatic Circulator is notapproved to handle flammable fluids.

WARNINGHandling and disposal of liquids other than water should be donein accordance with the fluid manufacturers specification and/orthe MSDS for the fluid used.

WARNINGThe user is always responsible for the fluid used. Never use corro-sive or flammable fluids with this unit.

WARNINGEnsure, when selecting the heat transfer fluid, that no toxic gasescan be generated. Inflammable gases can build up over the fluidduring usage.

CAUTION

Always adjust the unit's software to the fluid used.


4 Installation4.4 Fluid considerations

NOTICE

Water/ laboratory grade ethylene glycol mixtures require top-offswith pure water, otherwise the percentage of laboratory gradeethylene glycol will increase resulting in high viscosity and poorperformance.

Do not use bath fluids that:

• are very highly viscous (much higher than 30 mPas at the respective working tem-perature)

• have corrosive characteristics or

• tend to break down at high temperatures

For fluid selection consider application requirements, operating temperature range,material compatibility, safety concerns, and environmental issues. Refer to Chapter 8Reference information, on page 85 for suitable fluids.


4 Installation4.4 Fluid considerations

4.5 Filling requirements

Introduction

WARNINGBefore using any fluid refer to the manufacturer’s MSDS and ECsafety data sheets for handling precautions.

This section outlines the filling requirements for MultiTemp IV Thermostatic Circulator.

Ensure the reservoir overflow located on the rear of the unit is connected toa suitable drain.

Note:

1 Start with 2.8 liters of fluid. Lift up on the fill panel on the front of the unit to removeit.

2 Insert the supplied funnel into the hose and slowly add fluid.

Due to the unit's plumbing configuration, adding fluid too quicklymay resultin overfilling - the fill level indication lags the actual amount added.

Note:

3 Ensure the fluid contacts the side of the funnel first, A when pouring fluid into thefunnel. Pouring the fluid into the center of the funnel, B, will cause air pockets andsubstantially slow down the filling time.

Since the reservoir capacity may be small compared to your application and air mayneed to be purged from the lines. Have extra cooling fluid on hand to keep the systemtopped off when external circulation is started.

CAUTION

Avoid overfilling, fluids expand when heated.

4.6 Draining

IntroductionThis section outlines how to drain MultiTemp IV Thermostatic Circulator.

WARNINGAlways use appropriate personal protective equipment during op-eration and maintenance of MultiTemp IV Thermostatic Circulator.

CAUTION

Before draining any fluid refer to the manufacturer’s MSDS and ECsafety data sheets for handling precautions.

CAUTION

If leakage occurs from the drain tubing on the front panel, hot fluidmay cause harm to personnel.

CAUTION

Drain the unit before it is transported and/or stored in near or belowfreezing temperatures.

1 Lift up on the fill panel on the front of the unit to remove it.

2 Pull the fill hose off the clips securing it to the unit.


4 Installation4.6 Draining

3 Keep your thumb on the end of the hose until ready to drain the fluid into a suitablecontainer.

Shipment/ StorageTransporting and/or storing the unit in near or below freezing temperatures requiresdraining. Do not store the unit below -20°C, and <80% relative humidity.

8.5 Suitable fluids

Suitable fluidsThe following table lists the suitable fluids. All heat transfer fluids are supplied with anEC Safety Data Sheet.

DescriptionFluid

Normal tap water leads to calcareous deposits necessi-tating frequent unit decalcification, see table on next page.

5°C to 80°C — DistilledWater or Deionized Wa-ter (up to 3 MΩ-cm) Calcium tends to deposit itself on the heating element.

The heating capacity is reduced and service life shortened.

Below 5°C, water has to be mixed with a laboratory gradeethylene glycol. The amount of laboratory grade ethyleneglycol added should cover a temperature range 5°C lowerthan the operating temperature of the particular applica-tion. This will prevent the water/ laboratory grade ethyleneglycol from gelling (freezing) near the evaporating coil.

-10°C to 80°C — 50/50Water with laboratorygrade ethylene glycol(CAS# 107-21-1, EEC#203-473-3)

50% laboratory grade ethylene glycol is the maximumrecommendation. Excess laboratory grade ethylene glycoldeteriorates the temperature accuracy due to its highviscosity.

Unfavorably high total ionized solids (TIS) can accelerate the rate of galvanic corrosion.These contaminants can function as electrolytes which increase the potential for galvaniccell corrosion and lead to localized corrosion such as pitting. Eventually, the pitting willbecome so extensive that refrigerant will leak into the water reservoir.

As an example, raw water in the United States averages 171 ppm (of NaCl). The recom-mended level for use in a water system is between 0.5 to 5.0 ppm (of NaCl).

Recommendation: Initially fill the tank with distilled or deionized water. Do not use un-treated tap water as the total ionized solids level may be too high. This will reduce theelectrolytic potential of the water and prevent or reduce the galvanic corrosion observed.
