Dahle North America is a subsidiary of Dahle Burotechnik GMBH of Coburg, Germany. The company was started in 1930 by Wilhelm Dahle, making pencil sharpeners. They diversified into scissors, shears, paper cutters and trimmers, and finally into paper and multi-media shredders. The North American head office is in Peterborough, New Hampshire. (Without meaning to be patronizing - it's truly amazing how much development and innovation can be applied to even the simplest things with sufficient attention).
Dahle classifies its shredders as follows: personal - up to 100 sheets per day; small office - up to 500; office - 5,000 to 15,000; departmental - 20,000 to 60,000; and high capacity - more than that! The company also has a shredder specifically meant for multi-media work - paper plus diskettes & other plastic stuff - which will do 2,000 to 8,000 sheets per day, so is thus intermediate between the small office and regular office capacities. There is a also a "deployment" shredder - a portable machine which is certified at the highest security level, for use in shredding secret material in the field.
All the Dahle machines will handle paper clips and staples, even the least expensive models; they all have an automatic on/off system and thermal protection for the motor. The smallest shredders have an 8 3/4" fee throat, can handle 10 sheets at a time, and run at 15' per minute. The largest, heavy-duty jobs will handle 85-100 sheets at a time, have a 17" feed throat, and run at up to 42' per minute with a 55-gallon output hopper. They have the bells and whistles expected: safety interlocks, automatic oilers, and feed tables and racks.
Published prices range up to $12,000 for the top-of-the-line heavy-duty models; prices for high-security machines are given on request. There are many dealers that handle Dahle machines so there will be no trouble in finding local support.
