Stokes Hot Rods are a type of over the side immersion heaters which have wide applications in Electroplating, AquaCulture, Fishery, Hatchery, Mechanical Services and many other industries. The elements are ceramic filled incoloytubes contained within an outer sheath of either stainless steel, titanium or vitrosol glass. Please refer to the Heatersolution Guide section of Technical Information to determine the appropriate sheath material.

1.1 VITROSOLStokes Vitrosol heaters are made from translucent fused silica which has an extremely low co-efficient of expansionand is inert to most acids. This makes it an ideal choice for the heating of acid solutions. Hence they are used inaqueous acidic plating solutions such as nickel plating, acid copper and chrome plating etc. They are also used inpickling tanks, eg. in Sulphuric acid and Hydrochloric acid pickling.

Note: Vitrosol is a form of glass and must not be used in hydrofluoric acid or strong alkaline solutions.

Protection from mechanical damage should also be considered. This can be achieved by means of polypropylene guard or PVC in the case of chrome or nitric solutions. Please refer to our Heater Guards section for further information.

1.2 TITANIUMStokes Titanium heaters can be used in a wide range of acid and alkaline solutions, but chemical attack can occur in some instances at varying rates, depending on temperature and concentration of the solutions. In electroplatingprocesses such as nickel plating it is advisable to connect the Titanium sheath anodically to prevent corrosion.

1.3 STAINLESS STEEL 316Stokes Stainless steel heaters are ideal for use in phosphating solutions and in solutions with an alkaline or neutral PH value. Certain acidic chemical processes recommend the use of stainless steel tanks but this does notnecessarily mean the use of stainless steel heaters. In these instances it is advisable to use Vitrosol heaters due to the chemical attack on stainless steel at the elevated surface temperatures of the heater tube. In brass platingprocesses, liquid ammonia must be used, not ammonium chloride, as the chloride will attack the stainless steel sheath.

The following shows the hot rod dimensions, and tank dimensions.

The Kilowatts required depends on type of solution, temperature difference, insulation, and heat up time. Refer toour Heater Solution guide to determine appropriate sheath material. Refer to our Technical Information for requiredkilowatts calculations. Please contact us if you need any assistance with the calculations of kilowatts required.

HEATERS

Fig.4 Typical installation

• Minimum Liquid level must be maintained at all times

• Max solution temperature not to exceed 65 °C

Where possible it is advisable to install heaters in multiples of 3 in order to keep the phases balanced. It is desirable to locate the temperature probe at a reasonable distance from the heaters in order to obtain accurate control. Solution level must never be allowed to fall below the cold zone of the heater or the heater will fail.

CAUTION

• Stainless Steel Heaters:

When using S/ Steel sheathed units, care should be used in preventing high temperatures being transferred up the sheath, otherwise melting of the PVC cap may occur.

• Vitrosol Heaters:

When using the Vitrosol heaters extreme care should be used to prevent thermal shock that could cause the sheath to crack. It is important therefore to maintain the correct solution level at all times.

This can be controlled automatically by the use of a level control unit used in conjunction with a solenoid operated valve to maintain the solution level, or a safety device to isolate the heaters in the event of rapid loss of solution.

• To improve heat up times it is recommended that the tank be insulated and have a top to reduce temperature losses.

• It is recommended to install earth leakage circuit breakers with all quartz heaters, in accordance with local codes.

Hot rod Teflon® (PTFE) heaters are manufactured from mineral tubular sheathed elements covered with PTFE sleeving. The PTFE is acid and temperature resistant up to 280°C and is the only heater that can be applied to solutions containing hydrofluoric acid or fluoride forms in chemical heating applications.

Hot rod Teflon® heaters are also suitable for other acid solutions and because of the low watts density loading can increase the expected life.

Hot rod Teflon® heaters are custom manufactured in various bending configurations and kilowatt ratings to suit your specific requirements.

PTFE has a good mechanical strength and does not become brittle.

Note: The element must not operate in sludge deposits that accumulate at the bottom of chemical tanks.

Teflon® is a Du Pont® registered name.

11.1 QUICK CALCULATION CHART FOR HEAT REQUIREMENTS

Note:

• These wattages are based on an 8 hour heat-up time with an ambient temperature of 21°C (70°F).

• Kilowatt ratings are calculated on enclosed tanks having 50mm insulation.

• To reduce heat-up time increase the wattage proportionately.

GUARANTEEStokes Synertec guarantee electric heating elements manufactured by it to befree from defects in workmanship and materials. Its obligations pursuant to this guarantee are limited to the repair or replacement of any such element whichproves defective within the guarantee period, or at Stokes Synertec’s optionrefund of purchase price. The repair, replacement or refund should be effectedupon the defective element being returned freight pre-paid to the RegisteredOffice of Stokes Synertec or to the offices of its accredited Electrical Agents.

Stokes Synertec shall not be responsible for the cost of removing any defective element or reinstalling the repaired or replacement element.

(Where Stokes Synertec supplies goods not of Stokes Synertec’s manufacturethe customer shall only be entitled to any such benefits as Stokes may receiveunder any guarantee given to it in respect thereof).

GUARANTEE PERIODTwelve (12) months from the date of sale by Stokes Synertec or twenty-four (24) months from the date of manufacture by Stokes, whichever period shallexpire first.

CONDITIONSThis guarantee shall not apply:

(a) If notice of the defect has not been given to Stokes Synertec within the guarantee period.

(b) To consequential damage arising out of the alleged failure of the elements supplied.

(c) If the heating element has been:(i) subject to misuse, abuse, negligence or accident;(ii) subjected to conditions giving rise to sheath corrosion;(iii) installed, maintained or operated otherwise than in the manner for

which it has been designed;(iv) operated on an electrical supply, the voltage of which varies more than

10% from the rated voltage applicable to the element;(v) used for any duty or subjected to any abnormal operating condition

varying from that for which it was supplied by Stokes Synertec.

Orders will only be accepted and all sales shall proceed subject to StokesSynertec’s general condition of sale, copies of which are available on request.
