The TCS 2 Gallon Duplicating Machine is fully automatic, and melts, conditions, and returns hydrocolloid material to ideal temperature for immediate use. Easy to use and maintain, simply add anti-freeze and plug into an outlet, no need for water connections. The Hydrocolloid Dispenser by TCS was engineered with a double boiler tank. This engineering doubles the life of hydrocolloid material by not allowing the material to burn by sticking to the sides of the tank. Furthermore, this allows the mixer to turn periodically instead of constantly, saving on electricity and needless use of mechanical parts.
