封閉式電爐亦稱實驗電爐、萬用可調電爐、是醫院、農牧、環保、大專院校、科研單位及工礦企業等部門實驗室的加熱設備。
Scope：
Stａnd closed adjustable furnace is siso named as experimental electric furnace. or allround adjustable electric furnace. which is the most commonly used heating equipment in experimental depadments in hospitals agriculture and husbandry industry. environmental protection industry. schools. R&D institutes. factories and mines. etc.
結構特點：
封閉式可調電爐是直式可調電爐的升級產品，其加熱元件采用電熱管經鋼板封閉后制成加熱平板,解決了以往可調電爐在加熱時,因液體外溢形成電熱絲斷裂的缺點, 耐用并且干凈,易保養。爐體外殼由優質冷軋鋼板焊接制成，表面靜電噴塑處理。電子式調壓、調溫器采用雙向可控硅控制電源對加熱功率進行無級調控，操作方便、節能、安全、發熱體壽命長。整體設計新穎，美觀、大方。
注意當電爐空燒時請立即關閉電源開關，以免燒毀加熱板。
C0nstruction features ：
The furnace body is made up of excellent steel plates. whose furnacedtsk is supported by pallet. It uses slate to educe heat insulation function. It.s electronic model applies bidirecttonal controllable silicamaterials to modulate the heating power in no leve; and ITs mechanic one abopts sorting switch to control the heating in levels. The productcan be operated conveniently. energy saving. safely and with longheating generator service life.
