Compressed air dehumidifiers of SD 4/28 YES-System series, can be used on all plastics transformation machines with throughput of up to 25 kg/h.

They can process plastic materials in granules or pellets (virgin and regrind).

SD 4/28 compressed air dehumidifiers main features are:

• Minimum energy consumption achieved with the revolutionary YES-System, that automatically adjusts the parameters and the process variables in ordert to get a flexible dehumidification system able to adapt to the real conditions of use in the department, with no stress on the plastic granules.
• Very compact thanks to the rational design and the exclusion of molecular sieve and process blower
• Minimum maintenance thanks to the quality of all used machine components.
• Reliability, ease and precision with system designed to maintain the properties of the processed plastic materials.

Single tower molecular sieve dehumidifiers are suitable for dehumidification of plastic materials in granules, pellets (virgin or regrind) for a throughput up to 50 kg/h.

Main features of single tower dehumidifiers are:

• No costs involved for cooling water consumption or connection. Fully automatic operating, only requires connection to the electro-pneumatic mains.
• Noteworthy saving of electric power thanks also to the air-air exchanger;
• Dew Point viewer with adjustable alarm threeshold (optional).
• Easy maintenance thanks to the modular construction which ensures extremely easy access/inspection of all machine components.

Single tower dehumidifiers, together with our process hoppers, can be installed directly on the trasforming machine or next to it, can include a suction valve and be mounted on specific mobile trolleys.

Options that can be integrated in the system:

• YES-System technology for smart energy management;
• Daily / weekly programmer;
• Auxiliary thermoregulator.

Twin-tower molecular sieve dehumidifiers of DDT series, can be used in all plastic materials transforming machines, with a throughput up to 3000 kg/h, thanks to the wide range of models available.

They are suitable for plastic materials in granules, pellets (virgin or regrind), micro-granules and highly dusty flakes.

Main features of DDT series dehumidifiers are:

• Dehumidified air regeneration which enable lower residual moisture content in the molecular sieves, and consequently less wear and longer life of the sieves.
• Easy maintenance thanks to the modular construction which ensures extremely easy access/inspection of all machine components.
• Noteworthy saving of electric power thanks to the “passive rotation” operating cycle of the twin desiccant beds make this series the absolute ultimate in the field of dehumidification.
• Possibility of further energy saving with the revolutionary YES-System, available as an option;

DDT models from 140 to 800 have the following exclusive features:

• No costs involved for compressed air and cooling water consumption or connections. Fully automatic operating, only requires connection to the power mains.
• Gradual cooling system allowing to increase more and more performance and life of molecular sieves.
• Energy recovery from the return air to the delivery air through the exclusive heat exchanger.

MSM, at the forefront in the field of drying and dehumidification, with its long experience, thanks to the modularity and wide range of its products, is able to study the best solution for the treatment of plastic materials, with focus on rationalizing the customer's production system and maximizing energy savings.

Single hopper treatment

It's the traditional system, dedicated to the single material with dehimidifier/dryer serving one hopper only, in the ground configuration with trolley and suction valve, or to be installed directly on the transforming machine.

Multi-hopper treatment

It's particularly useful in case of multiple material treatment (different materials and/or colours), with possibility of thermoregulation to be the same for all hoppers or differentiated by hopper (in case of DDT dehumidifiers, with the use of PR series preheaters).

Hopper can be mounted on specific trolleys or supporting structures, or installed directly on the transforming machine.

Centralized treatment

Both solutions above can be integrated in a central conveying system for maximum rationalization of raw material storage and treatment.

Dehumidification/drying can be located, for instance, directly in raw material storage area. Materials in treatment are eventually conveyed to the transforming machines through the central conveying system.

Insulated process hoppers, designed specifically for optimization of drying and dehumification treatments, have the following main features:

• Fully made in AISI 304 stainless steel
• Full insulation with rock wool with a high degree of thermal insulation
• Wide range of models with capacity from 15 to 6000 liters to satisfy any production need
• Very easy to inspect and clean

For integration, depending on the application, trolleys or support structures are available as an option.
