Laboratory Ovens - Welland range - 300°C
A modern range of ovens, with a maximum operating temperature of 300°C, providing a combination of excellent performance and reliability.

Increased power and low thermal mass encased fibre insulation ensure both fast heat up times and reduced recovery times.

Reduced holding power once at set temperature, together with the insulation, makes the range economical. Cool safe outer case temperature.

Both gravity and forced air circulation models are available with a wide choice of control options, allowing the most critical performance criteria to be met. Where processes involve the liberation of flammable vapours, a stoving and curing option is available and for processes involving large amounts of water, a moisture extraction option is available.
