High Grade Dehumidifying Dryer DEZAT

Higher grade than the NS series
Thorough drying of transparent resins

- Inherits the performance of the DEZAT NS with upgrades for clear resins
- Heatless dry air unit that delivers cryogenic dehumidification
  at –50˚C and maintenance-free operation
- Contamination-free owing to automatic butterfly shutters and
#400 polished SUS304 in contact with stock
- Lineup of dedicated KV series pellet tanks available

Drying capacity is given for PC drying.
Round System

■ Round System

STOLZ’s Round System supplies and circulates dehumidifying air of –50˚C generated by a heatless dry air unit through a closed system consisting of a completely airtight blower, filter, heater and dryer drum. Because it does not contain complicated processes for recooling or reheating, the system saves on energy and does not require cooling water.
  Moreover, it is maintenance-free because the air used for drying is not recuperated and the heatless dry air unit can withstand long-term use without performance losses caused by special designs.

Closed conveying system

■ Closed conveying system

The closed conveying system transfers plastic to the molding machine over an airtight circuit using suction force. Because secondary air is not drawn into the circuit, it shuts out moisture found in the surrounding environment, thus enabling thorough drying.

Automatic butterfly shutter

■ New high capacity NS-400V in the lineup

New to the lineup is the NS-400V with a loading capacity of 400 kg that exhibits its full value in molding operations for large transparent resin products.

■ Contamination-free

High performance automatic butterfly shutters are equipped at the top and bottom of the drying drum. Furthermore, all surfaces that come in contact with stock are made of SUS304 and polished to a #400 finish to prevent contamination and improve the molding quality of clear resins.

■ Easy maintenance

The drying drum is structured with wide openings at the top and side so that stock loading and maintenance are speedy and easy.

■ Stock feeding to 2 molding machines

The NS-V series can supply dried resin stock to 2 molding machines using multiple feed branch lines and air branch valves.

■ Line filter

A line filter can be installed on the molding machine hopper to thoroughly remove dust. Applicable models are shown in the table. Specify hose length separately when ordering.

■ Hopper plate and attachment for installation on molding machine

An installation plate and attachment are separately needed to install the hopper on molding machines that do not meet the standard specifications shown in the table, therefore indicate those specifications when ordering.

■ Hoses

Specify the length of the bare stainless steel flexible hose used to convey stock. (Ferrule ends, 0.5 m markings from 1 -- 5 m, lengths over 5 m possible by connection) Suction hoses of the same length as material hoses are automatically selected.

■ 300 kg level gauge

A paddle-type level gauge is installed on the drying drum. It allows users to set loading capacity to 300 kg.
NApplicable only with the NS-400V.

■ Circulation filter

A 3 µm filter unit is located between the blower and heater to increase the clean factor of circulated drying air.
Applicable only with the NS-400V.

■ Dust removal device

This device removes dust that infiltrate resin before being fed to the dryer.
Applicable only with the NS-400V.

■ Power cable

The standard power cable is 4 m long, but other lengths are available.

■ Color

Provide samples if desiring colors other than the STOLZ standard color (shown in photos).
