Union’s Dialog 700 computer system, which is programmed to include operating instructions to suit the individual business, was highlighted by the company at this year’s giant Clean exhibition in the US.
The company has been innovative in its approach to simplifying routine tasks to keep a perc or hydrocarbon drycleaning machine performing at optimum level.
Parrisianne, the UK distributor of Union equipment, works with the Dialog 700 to ensure that UK-applicable machine maintenance is easily conducted by routine.
At the start of the working period, supplies are turned on and the machine is warmed by using the drum deodorisation program – this takes about eight minutes to complete and the first load of the day can be prepared during this time.
In the middle of the work period, program 13 is selected – with this a general load of medium-soiled work may be processed and filter maintenance conducted simultaneously. A computer signal activates a filter drop during the process cycle.
At the end of the work period, progam 18 is chosen to bake the still residue, removing solvent, and to pump residue to the waste bin. The baking/pumping activity takes about four minutes. After program 18 has been run, the machine may be closed down.
The lint screen arrangement and button trap need to be inspected/cleaned on a daily basis, and the water separator has to be regularly drained and cleaned. Primary and secondary lint screens have been brought together in one streamlined unit, and a spray jet for automatically cleaning the primary screen is an option. Back plate washing remains a standard feature.
Efficient operating costs are featured across the machine range. Notable is how heat from the distillation process significantly assists, through a secondary heat pump, in raising the drying air flow temperature. Union’s adjustable drying control allows an extension of the drying phase of the cycle by up to 50% which gives useful additional processing flexibility.
Cleaning program alterations are straightforward as functions anywhere in the program may be amended. There is no need to go through a whole program, step by step. Extremely easy programming is facilitated with a flow chart helper. A password system means only authorised personnel are able to introduce new programs or alter existing ones.
Fast, efficient, safe distillation in hydrocarbon machines is achieved by Union with the use of a pre-distillation solvent holding tank – in the case of the HL735 model the capacity of this tank is 75 litres.
The drycleaning machine’s Dialog 700 computer system monitors distillation activity and, when appropriate, signals for another five litres of solvent to be transferred from the holding tank to the still. Distilling batch by batch is effective in preventing boil-over. The distillation process is enhanced through improved water separation. The rate of distillation can be regulated by vacuum control.
To meet Health & Safety Executive requirements, the vacuum safety system for hydrocarbon machines is electro-mechanically controlled and hard wired.
For flexibility and efficiency, the main motor of hydrocarbon machines, and the drive for the fan unit, both have inverter control. With a Union hydrocarbon machine, drum speed during extract is up to twice as fast as that with a perc model, and the inverter control allows extremely fine tuning of the extract phase of the cycle.
All perc machines can be fitted with a fabric treatment spray system, additional carbon absorption units, and an electronic ppm tester/controller. Inverter drive, standard on hydrocarbon machines, is available as an option on perc models.
