Walk-in climate chamber or Reach-in climate chamber?

Find the best solution for your application

 

In addition to an extensive range of traditional reach-in climate chambers, BINDER’s WIC series provides walk-in climate chambers for applications in the pharmaceutical, food, and cosmetics sectors. But what are the differences between environmental walk-ins and reach-ins and what advantages does each solution offer for users?

Environmental Walk-in chambers (or walk-ins for short) provide much more space compared to traditional reach-in climate chambers. They can be a good alternative when testing or storing large quantities or bulky packaging in particular.

BINDER walk-in climate chambers and reach-in climate chambers are designed and built to offer outstanding constant climatic conditions. They are ideal for long-term and accelerated stability testing in accordance with guidelines ICH Q1A (R2), VICH GL3, and WHO climate zones I to IVb, as well as for shelf-life studies and storage. The interior coating of both variants is made of grade 1.4301 stainless steel. In addition, walk-ins and reach-ins from BINDER offer qualification documentation including IQ, OQ, and PQ.

BINDER walk-ins feature extensive shelf space to accommodate large quantities. This is useful if all samples need to be tested under the same conditions. However, if different climatic conditions need to be simulated at the same time, this is not possible with a walk-in. In such cases, the ideal solution would be to use several reach-ins instead.  The decision regarding whether you opt for walk-in or reach-in solution should not be taken lightly. Users should precisely define their own requirements in advance, including any long-term needs. The following properties should be considered when making a decision:

 

Walk-in climate chamber

Important product features at a glance:

Interior volume: 12, 18, or 24 cubic meters

Shelf space: 12, 17, or 22 square meters

With accesory shelf set for WIC and four shelf levels (standard).
The shelf set is not included in the scope of delivery of WIC.

5,8  8,1 or 10,3 cubic meters shelf area

Shelving system is not included in the standard scope of delivery and must be ordered separately.

Significantly more space required due to external air conditioning unit, maintenance walkway at least 500 mm wide required; alternatively, the air  conditioning unit can be positioned next to the door

Temperature accuracy: ±1.5 K

On-site assembly required, chamber components are delivered on pallets. Clarification of structural aspects such as evenness of floor, dimensions of doors, elevators, etc., position of electricity and water supply required

No special water quality requirements as humidification and dehumidification is controlled via a dew point bath. If the water is very hard, water softening can extend the service intervals.

 

Constant climate chamber (reach-in)

Important product features at a glance:

Largest KBF-S 1020 BINDER constant climate chamber: 1 cubic meter

Largest KBF-S 1020 BINDER constant climate chamber: 3.5 square meters with three shelves (typical operation)

The standard scope of delivery of the KBF 1020 includes two shelves.

 

0.76 cubic meters

In accordance with the definition of usable space  for BINDER reach-in units: Internal dimensions minus ten percent.

Less space required

Temperature accuracy: ±0.3 K

Flexible installation options and transport on casters, no on-site assembly required

 

Operation requires deionized water, as humidification is achieved by steam generation.
