Product Detail



Key Features

Below are the standard key features of a Rolt Dryers.

  1. ๏The Rolt tower dryers save a great amount of space.

  2. ๏The material is held to a vertical conveyor and it is therefore possible to use powerful jet blast air drying among other methods

  3. ๏Heater power is regulated with ‘proportional integrating, differentiating’ heat control, which ensures a steady flow of drying air at the set-point temperature.

  4. ๏A proportion of the hot air is recirculated.

  5. ๏The towers can be fitted with web tracking equipment which enable the dryer to run thin substrates.

  6. ๏The dryer has independent speed controls, so the drying can be matched to conditions – the rest of the machine automatically adjusting to keep pace with it.

  7. ๏Different jet boxes provide for hot air drying as well as for cold air conditioning of the material. A cooling section can be provided to reduce the heat retained by the material.

  8. ๏All the dryers have features for economy, can be used in multiples and have different arrangements for heating and flow.

  9. ๏Back heat, front heat, regulation by solvent evaporation, IR, and baking oven versions are all standard options.

  10. ๏All the dryers can be fitted with UV or IR.

 



5M2 High Temperature Dryer

5M-2 An insulated medium temperature dryer up to 130°C.

 



Product Overview

A vacuum box is fitted before the dryer to ensure that thin film is aligned     before entering the dryer and to ensure consistent and accurate tracking through the dryer.

Vacuum is used to hold the printed material to a vertical conveyor and it is therefore possible to use powerful jet blast air drying among other methods.

Temperature set-point range from ambient to 130°C (266°F). Heater elements of 16kW are fitted inside the dryer.

The dryer has independent speed controls, so the drying can be matched to conditions.  The rest of the machine automatically adjusts speed to keep pace with the dryer.

The total drying length through the dryer is 7.3m (24’).  Extra sections can be added to the dryer to increase drying capacity.

Air flow is cascaded through the dryer to save the heating required to maintain temperature at set-point and thus saves energy.

Clean dry hot air is used to dry the web exiting the dryer.  Partly saturated air is used to dry the web as it enters the dryer.

Efficient jet air blast drying tunnels is installed throughout the drying sections.

The dryer has a fully insulated skin to minimise heat loss to the surrounding atmosphere.

The dryer is fitted with a 127mm (5”) solvents exhaust line.
