Melting Tanks

Chocolate melting tanks keep large quantities of melted chocolate at a controlled temperature, ready to feed tempering machines, enrobers or moulding lines. Keylink does not supply these tanks directly; they are built by our sister company KeyChoc as the Infinity MT Series at its production facility in St Helens.

Which Infinity Melting Tank Sizes Are There?

Each Infinity MT tank is temperature-controlled and fully jacketed. The MT250 holds 250kg, the MT500 holds 500kg and the MT1000 is the largest in the series. Every size also comes as a P version, which adds an onboard pump for easy discharge.

What Can a Melting Tank Hold Besides Chocolate?

KeyChoc describes the tanks as suited to a wide variety of food products, from chocolate and other fat-based masses through to wax for candlemaking.

Who Handles Orders and Support?

Every machinery enquiry and order is handled by KeyChoc directly, so you deal with the team that builds the tanks and the local engineers who look after them. Its range also covers the Infinity tempering machines and the automatic moulding line.
