Model: 7CD  – 7 lt Digital Temperature Controlled Electric Double Boiler

Digital Temperature Controllers provide excellent temperature control, fast reaction and intelligent operation allows the water jacket to be managed at as high as 100℃ and will cycle the heating element automatically to maintain temperature, simply set the desired water jacket temperature up to 100℃ and the controller will manage the temperature.

For more information watch our videos in the video tab, they explain why the double boiler method is so important and still the fastest way to do it correctly, share this with your friends like us on Facebook and help us help people to be successful by making an ethical and quality product.

Brass Product Tap.

Recommended for product temperature up to 85℃ – For higher than 85℃ product temperature please contact us for recommendations and advice, to achieve higher temperature digital models used with a thermal jacket can obtain temperatures up to and slightly over 90℃ understanding the water jacket is limited to the boiling temperature of water and some heat loss does occur in the transfer process.

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. First fill the water jacket with demineralised water – demineralised water is a low cost product that can be purchased at supermarkets and hardware stores for around $4 for 5 litres, once filled the demineralised water is left in the unit for it’s entire life just topped up as required, demineralised water protects internal components extending unit life and improving serviceability for many years.
  2. Plug into power.
  3. Heat unit to desired temperature.
  4. Add product and heat product to required temperature.
  5. Stir occasionally until the product is stabilised at the required temperature.
  6. Make Products.

Units will have some marks from the manufacturing processes.

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.
