ICE THICKNESS REGULATOR AL 900

ELECTRIC CHARACTERISTICS

-Supply: 230v. ca 50/60 Hz

 -Supply: 115 V. c.a. 50/60 Hz.(it depends on your order)

 -Absorbed power: 3 VA Max.

 -Relay: 1 contact

 -Maximum intensity in relay contacts: 19 A (supported charge)

 -Type of drill: 2 electrodes

 Voltage average in terminals of the drill: 33 uv (microvolts)

 -Force average in terminals of the drill: Inf.a 1ua (microamp)

 -Critical resistence activ.: 35.000 ohms

 -Critical resistence deactv.: 105.000 ohms

 -Temperature of running: -10ºC to 70ºC

 -Control activation: control. activates through water conductivity with a reading wait of 30 seconds.

 -Control deactivation: control deactivates when the ice covers the drill, with a forced stopped of 20 minutes (AL.901) and 62 minutes (AL.908) by means of a microprocessor predeterminate for this control.

 -Checking at the stop cycle: it can be checked during the stop cycle if the ice-thickness control is activated just by desconnecting the beer cooler and connecting it again. The cycle goes to 0 and it will give us a reading 30 seconds after we connect the machine again. If the reading of the microprocessor corresponds to water among the terminals of the drill, it will go on until it finds some ice. If, on the contrary, when doing the reading, it detects some ice, the cooler will stop after 30 seconds as a normal cycle.

-Control starter: pitting the drill, instant starter.

 -Control stop: unpitting the drill, instant stop.

 -In this operation no cycle of forced stopping is activated.

   -Completely compatible with models AL.100, AL.101, AL.108, AL.111.

 -Band of use from 35 to 3500 microsiemens ofwater conducivity at 0°C according to EEC TR = 25ºC.

 -It does not cause electrolysis, so we avoid:

• Contamination of the drill and, as a consequence, a service calling.
• Possible perforation of the coils which may cause loosing product and having to change the whole coil.
• Possible evaporator perforation which may damage the refrigerating equipment by flooding.

 -The design let's the ice block s maintenance time not to exceed two startings per hour.

 -Example:

• Water in the tank: 550 microsiemens at 0ºC.
• Surrounding temperature: 22°C.
• Heat contribution by irrigation: 140 Kcal/h.
• 8 hours producing ice.
• 16 hours of ice maintenance.

-With the new ice-thickness controllers we improve the features so that if we compare them with those already existing in the market we get:

• 31.000 compressor starting less per year.
• 31.000 fealures less of the ice-thickness control relay.
• 31.000 fealures less of the compressor starting relay.
• 1.300 hours less per year ofrunning, both the compressor and the fan.
• As a result of the saving, we also get 31.000 strokes less of the refrigerant liquid to the compressor when starting.
• We economise energy: 770Kw/year.
• As it works more time on recovering, we get a better output of the compressor which works for a longer time with the refrigerating system well-balanced.
• As the cycles of ice-recovering are longer we help the return of oil towards the compressor.

 -The above mentioned datas will change in accordance with the water conductivity (microsiemens) , the surrounding temperature or the heat contribution by irrigation.

 -The new ice-thickness controllers contribute to make cheaper the costs of maintenance of the machine.

 -Our ice-thickness controllers follow the norms of the Electromagnetic Compatibility Guidelines 89/366/EEC and its modification 92/31/EEC and with the Dielectric Guideline oí Rigidity BC 73/23/EEC.
