Model: 15SD  – 15 lt Digitally Controlled Electric Double Boiler.

Digital Temperature Controllers make higher product temperatures achievable and provide precise temperature control, fast reaction and intelligent operation allows the water jacket to be maintained at as high as 100℃ without rapid boiling, the controller will learn and cycle the heating element automatically to maintain temperature, simply set the required temperature up to 100℃ and the controller will do the rest, capillary style thermostats (dial type) capillary style thermostats are very good however slower reaction means the temperature can’t be set higher than 90 to ensure the water jacket doesn’t rapid boil form temperature runout.

Stainless Steel Product Tap.

Recommended for products requiring temperature up to 90℃

An Electric Double Boiler is the single best investment any small business can make, electric double boilers will allow the user to do in few hours that likely previously took a few days, simple to maintain and use while producing a consistent and high quality product.

Ideal for hobby or small business.

There’s nothing better than an electric double boiler.

The Basics

  1. Fill water jacket with demineralised water – demineralised water is low cost and is purchased from supermarkets and hardware stores for around $4 for 5 litres, once filled is left in the unit and just topped up as required, demineralised water has no harmful minerals that tap or tank water contain and will protect internal components.
  2. Heat water jacket to desired temperature.
  3. Add product and heat to required temperature.
  4. Stir occasionally to stabilise product temperature.
  5. Make Products.

Units will have some marks from the manufacturing processes.

Note: High Viscosity Products:

If your intention is to make product that are quite viscos and set quickly we recommend model 15R or 15DR, please contact us prior to purchasing if you would like any product advice, in some cases an electric heat gun is used to warm the tap slightly before pouring for products that set quickly.

Design Capability

Water boils at 100℃, however it is not possible to achieve 100℃ product temperature with double boilers, the main reasons for this are ambient (room) temperature fighting to cool the unit body and heat loss from transference through the wall of the internal product chamber, for these reasons we recommend the units for products up to 90℃, it may be possible to achieve up to 95℃ if the unit body is insulated, the work area is not below 20℃ and extra heating time is added.

Double Boiling Method explained

An electric double boiler means the unit has a water jacket around the outside of the product chamber providing a much larger heating surface, the water jacket protects the product from high heat that is produced by the electric element when it’s heating, the water jacket thermostat controls the heating process, once heated up product is placed into the product chamber and the heated water in the jacket melts/heats/emulsifies/separates depending on the product being used from the base and the sides to the desired temperature.

The product tap passes through the water jacket and is surrounded by hot water heating it.

Product is stirred periodically to stabilise temperature before pouring.

Product temperature is maintained by the water jacket thermostat allowing the user to spend time preparing for the final product.
