Abstract

A filter heater arranged to enclose a filter, wherein said filter heater comprises two similar halves each having a protruding handle on one side, whereby the handles are kept together by a spring mechanism such that pinching the handles towards each other will force the sides of the two halves opposite the handles from each other.

First claim

What is claimed is:

1. A filter heater arranged to enclose a filter, the filter heater comprising:
two similar body part halves, each body part half comprising:
a resistive heater disposed on an inside thereof and configured to heat the filter, and
a protruding handle on one side thereof,
wherein the protruding handles are kept together by a spring mechanism such that pinching the protruding handles towards each other will force the sides of the two body part halves opposite the protruding handles open away from each other, and wherein the filter is to be disposed therein between the two body part halves and when releasing the protruding handles, the two body part halves close together, thereby encompassing the filter therein.

2. A filter heater according to claim 1 , further comprising protruding parts from each body part half adapted to be held together in a stand when the filter heater is closed around the filter.

3. A filter heater arrangement comprising a filter heater according to claim 1 and a stand, wherein said stand comprises at least three legs and a filter holding part elevated by the legs from a surface where the stand is provided, wherein the filter holding part of the stand is arranged to receive protruding parts of the two similar halves of the filter heater such that the halves are kept together in the stand.

4. A filter heater arrangement according to claim 3 , wherein said filter holding part comprises an opening for receiving a tube attached to the filter.

5. A filter heater according to claim 2 , comprising electrical heaters on the inside of the two similar body part halves adapted to heat the enclosed filter.

6. A filter heater arrangement comprising a filter heater according to claim 2 and a stand, wherein said stand comprises at least three legs and a filter holding part elevated by the legs from a surface where the stand is provided, wherein the filter holding part of the stand is arranged to receive protruding parts of the two similar body part halves of the filter heater such that the body part halves are kept together in the stand.

7. A filter heater arrangement according to claim 6 , wherein said filter holding part comprises an opening for receiving a tube attached to the filter.
