Ecodrie in Wijchen approached Discom BV with a request to develop a silencer configuration for a variety of hoisting units. The engines are usually used in severe circumstances. The engines therefore have to operate at full load immediately after they are started. In response, Discom BV supplied a silencer with a special entry and exit which is mounted to the exterior of the machine. Depending on the customer’s wishes, these silencers can be made from steel S235 JR G2 or various sorts of stainless steel.
