miniClima EBC10, EBC11 and EBC12 constant humidity generators for up to 10 m³

Moisture stabilizers miniClima - humidification & dehumidification precisely controlled

Moisture stabilizers "EBC" are small devices for regulating the relative humidity in largely air- and vapor-tight sealable containers. Basically, "container" can stand for many applications (museum showcases, depository cabinets, control cabinets ...).

The showcase and the miniClima constant humidity unit together with the connecting hoses form an air-tight recirculation system.
The measured value for the relative humidity is recorded inside the showcase by a small humidity sensor and compared in the controller with the set humidity setpoint. In accordance with the setpoint / actual value deviation, the controller effects a slow, state-of-the-art air state change that is gentle on the exhibits.

Functionality

Each EBC 10/11/12 series is a fully functional main and slave unit. The hierarchical status into which the EBC changes can be selected by plugging in the corresponding cable: A miniClima humidity / temperature sensor will turn the device into a main device ("master"); If, instead, the control line of a preceding EBC is detected, the device in question will be lower in hierarchy and henceforth behaves as its "slave".

Dehumidification

Excess humidity condenses on a Peltier-cooled surface. The condensate is collected and pumped out of the recirculation system. Longer dehumidification processes are regularly interrupted by short defrost cycles.

Humidification

Condensed / distilled water is pumped from the water bottle into the recirculation system and evaporated. For refilling only distilled water may be used.

Data logger

The data logger hardware is a standard feature in each EBC. The data logger software is included with the delivery or can be downloaded from our websits. This not only allows you to read out approx. 15,000 temperature and humidity values, but also to view the alarms that have occurred as well as the settings made at the EBC. In addition, live data can be monitored via the RS232 interface. The data logger automatically measures and saves every 30 minutes, you do not have to start it specifically. You can modify measuring intervals in the software.

Alarm

If the setpoint is not reached after 90 minutes, a visual alarm message is issued. This should also be interpreted as an indication of a possible leak in the air circulation system. In addition, the device has a potential-free contact for an external alarm, which you can use at your own discretion.

Water level message for the bottle

By default, each EBC is delivered with an alarm sensor against overflowing the water bottle (max. message). Optionally, the device can be supplied with an additional lower sensor (max. and min.)

2-liter bottle / positioning bottle

All units of the current series can be optionally equipped with a 2-liter water bottle (instead of the standard 500ml bottle). The EBC 12 comes standard with a 2-liter water bottle.
The water bottle can be placed next to the EBC or in front of it, giving you more options to position the device in confined spaces.

Positioning of equipment

Often the devices are placed in the base below museum showcases. In this case, the base should be well ventilated and thermoinsulated against the cabinet interior, to make sure the warmth of teh EBC-unit won't reach the showcase. Alternatively, the device can also be accommodated externally, up to 8 - 10 m away from the showcase. In this case, select the option "stronger fan" for the units and specify the desired length of the sensor cable and the desired hose lengths.

Special equipment

2-liter bottle

The 2 l bottle is offered as an optional extra (surcharge) for all units of the current series. In this case it replaces the standard bottle (0,5l).

In most cases, however, it is not necessary to replace the standard bottle, because after a certain period of time, the devices will have stabilized the moisture level in the showcase, thus regulating the moisture content with the help of the 0.5l bottle without constant refilling or emptying leaves. However, there are cases in which an increased supply or removal of water will be expected over a longer period of time, such as when there are exhibits in the showcases which either only release or only absorb a great deal of moisture.

The option of the larger water bottle is recommended by us only for such special cases. For all cases - large or small bottles - it is important that the water level in the bottle is checked regularly to ensure undisturbed humidity regulation.

Lower water level alarm for the bottle

To alert when the water bottle becomes empty.

Recirculation filter / recirculation fan

The air recirculation filters "FLT" are offered as special equipment (surcharge) for all devices (upgraded according to air performance) of the current series.

The integration of a FLT into the circulating air hose system takes place - as usual from the EBC and the showcase - via hose fittings. The filter capsules are equipped as standard with dust filter mats and activated charcoal (sequence: filter mat F3> activated charcoal> filter mat F5), but can also be designed differently on request.

Technically speaking the filter and its EBC form a unit. The pressure drop caused by the filter has to be compensated by a stronger fan. Standard equipped EBCs should therefore not be operated with recirculating air filters. Conversely, it is equally unwise to connect an EBC equipped with a stronger recirculation fan directly to a display case without a recirculation filter (or without another air resistance increasing cause). Excessive air velocity could adversely affect the exhibits and / or the dehumidification capacity of the EBC.

WiFi-Port

With the help of the boxes, up to six showcases can be connected to one device. It should be noted, however, that the max. reduced air volume of the devices to be processed by a factor of 0.8. Ie: with an EBC 10 you can now instead of max. 3 m³ only 2.4 m³ (sum of all connected showcases) edit; with an EBC 11 only 4 m³ (instead of normally 5 m³).

The air distribution boxes are additional parts subject to extra charge. Two sizes are available: a small box for the humidity constant device EBC 10; a big one for EBC 11. Per unit one pair of boxes of the same size are needed (return air). Next to the boxes corresponding hoses and hose fittings will be supplied as well as blind caps for closing the unused outlets.

The diameters of the holes on the showcase change as follows when using the boxes: EBC 10 - instead of 25 mm now 20 mm; EBC 11 - instead of 32 mm now 25 mm.

IMPORTANT: The air distribution boxes should only be used in cases where sufficient air circulation can be ensured for all connected showcases and also only where separate regulation of the individual showcases is not desired or (possibly for later) planned (all connected showcases are operated by one device, i.e. moistened to the same nominal value).

It should also be noted that the air hoses that lead from the box to the individual showcases must be kept the same length (even if circumstances make it possible for individual showcases to shorten the hose!), Otherwise there will be different air currents in the showcases come, so also to different and possibly no longer regulated humidity values.

Remote control

In its standard configuration, every EBC has an integrated control unit for entering the RH setpoint and other parameters as well as for outputting the actual states. Alternatively, this integrated unit can be replaced by a remote control.

For this purpose, there is a 25-pin D-SUB connector on the front panel of the appropriately adapted EBC instead of the integrated control unit, to which the remote control element can be connected with a cable up to 2m long.

The remote control is - like a standard EBC - equipped with LCD display and the same input buttons. With the two mounting brackets supplied, the control element can be mounted flush with either its front or with its back.

External alarm device

Alarm and operating LEDs, which are controlled via the 6-pin plug-in contact on the EBC front.
