Model GD1021 Laboratory Glassware Dryer

1.0 General Description

The Model GD1021 Laboratory Glassware Dryer is a high capacity cabinet dryer specifically designed to dry laboratory glassware of all shapes and sizes as well as other items used in the laboratory environment. Adjustable shelves allow several loads of glassware to be dried at the same time.

2.0 Dimensions SIZE (Width” X Depth” X Height”)

*Note: Dimensions are maximum chamber opening sizes. Actual Load size must be smaller to allow for clearances. Custom chamber sizes can be provided as required.

3.0 Models Available

4.0 Automatic Temperature Regulation

4.1 All models shall incorporate analog temperature controls adjustable from the front panel.

4.2 Steam Heat

4.2.1 Heating system shall consist of a commercial steam to air heat exchanger, complete with valves, strainer, condensate trap and all other necessary trim. Unit shall be easily removable for cleaning or repair.

4.3 Electric Heat

4.3.1 Heating system shall consist of Finned Strip-type heating elements with contactor, short circuit and over-temperature protection and all other electrical appliances necessary in accordance with NEC and UL specifications.

5 .0 Timer Control

5.1 Unit shall incorporate a front-panel mounted timer which shall control the drying cycle time.

5.2 All controls shall be of industrial design and type, in order to resist the extreme environmental demands of the washroom. All electrical wiring, operator interface controls and circuits shall be protected in accordance with NEMA, UL and NEC standards.

6.0 Insulated Exterior

6.1 T he exterior of the machine shall be fully insulated with 2" (5.08 cm) of rigid insulation covered by a Stainless Steel jacket for protection. This insulation shall be an integral part of the machine, designed to limit radiation loss to the surrounding air.

7.1 A full set of manuals explaining machine operation and controls shall be provided.

7.2 A complete list of purchased parts including original part numbers, where the parts were purchased, and the nearest local distributor where the parts can be purchased shall be provided as a standard part of the manual. All purchased machine components such as valves, etc., shall be entirely non-proprietary and available for purchase freely and widely through normal industrial supply outlets.

8.1 Items to be dried shall be placed in the chamber. The door shall be closed and the cycle timer set. Treatment shall commence and continue automatically to the end of the cycle. Once the treatment cycle is complete, the operator shall open the door and remove the dried items.

30.0 Details of Construction

30.1 General

30.1.1 All interior and exterior parts shall be of Type 304 Stainless Steel or other Non-Corrosive materials.

30.1.2 All electrical assemblies, piping assemblies and mechanical apparatus shall be designed for, and be appropriate for use in, a high temperature sanitary wash-down environment. All components shall be selected for their ability to perform for long periods of time in the adverse and high production environment of the laboratory washroom. Each purchased part and each engineered part and sub-assembly shall be scrutinized and all specific design decisions shall be made in the light of these basic criteria.

30.1.3 All purchased components shall be un-modified, off-of-the-shelf items available to the owner in his locality, should he need them.

30.1.4 Original manufacturers' part numbers and descriptive information for all purchased parts shall be made an integral part of the service manual information provided at time of installation, and every effort shall be made throughout the life of the machine to assist the owner in acquiring any parts needed.

30.2 The door of the dryer shall be of double-walled stainless steel construction, 1" thick, and filled with insulation.

30.3 Temperature shall be controlled up to 240^o F (115.56^oC)
