PASSING HEATER

An electric heater in the cold season is necessary, for example, when working in unheated rooms. In the sale of these heaters, of course, available, but to make it yourself quite easily, thus saving a substantial amount in the family budget and honing your skills of craftsman, which I did.
If we evaluate, we offer readers of the heater as a whole, it can be described as: domestic, universal and pass. The first distinguishing feature indicates that it is intended for household needs and is powered by a single-phase network with a voltage of 220 V.

The second quality means that the device can be used not only for heating but also for drying — plant food during its preparation for long-term storage, as well as clothes and shoes.

The latter figure is partly open design of the heater, which further and speech will go.

The “heart” of the device are two air heat electric heater (PETN), connected in series. This connection happens only moderate heating of the heating elements and does not require a fan for venting and cooling. The selection of heat (which is fairly intense) is due to the convection of the outflow of heated air and inflow of more cold.

Contribute to this and numerous dural radiators, pressed onto a tubular steel sheath heating elements (therefore, these Heaters called air).

Universal appliances, a walk-through the heater-dryer:

1—wall; 2 — leg; 3 — adapter (brass, sheet B2, 3). 4 — power cable (plug is not shown); 5 — fasteners (bolt M4 8 PCs); 6 — baffle (2 pieces); 7—spacer (4x); 8 — heater with radiators (2 pieces); 9 — the grommet (rubber)

The series connection of the heaters together is carried out by adapter — brass plate. Using the same adapter to connect the heating elements and wires of the network cable.

Mounted heaters in makeshift housing made from galvanized sheet metal roofing steel with a thickness of about 1 mm (but can be of duralumin sheet). Body design folding, and therefore its elements: legs, walls and partitions — is implemented as a separate part. All of them have bent at 90° flanging, which act as stiffeners. After cutting of workpieces must be cleaned with a file within a circle of burrs and to dull the sharp edges. Then you should make a trial Assembly and adjustment of parts and to drill both holes for the mounting bolts in the connected elements.

The connection of all parts into a single structure is only eight bolts M4.

Various options of using the heater-dryer
(A—drying of fungi; B—drying of herbs; to dry the berries; D, for drying details):

1—the heater-dryer; 2—steel box; 3—clip (steel wire d3); 4—pin (steel wire d3); 5 — kidneys; 6—grid (2); 7—pan (steel sheet s1, 2); 8—hook (steel wire d1); number of parts in positions 3,4,5,8—on demand

To operate the heater must be installed on a fireproof base. Otherwise, under it it is necessary to enclose the metal sheet, and the sheet — pad of insulating material.

To use the heater as a dryer it is necessary to manufacture the casing from the same sheet as the body of the instrument. The casing will serve as the hub of heat, and a support for baking trays, skewers etc.

For drying mushrooms, you will need skewers, and for herbs and berries — mesh trays. The size of the skewers and trays should correspond to the length and width of the casing.
