Delta T Systems announced the appointment of HVAC veteran Bob Miller to its staff. In his role as HVAC specialist of the new Delta T Complete vessel ventilation program, Miller's goal is to set a new benchmark of reliability in marine heating, ventilation and air conditioning (HVAC) systems and to spearhead the HVAC portion of the new Delta T Complete program, which the company said was formed to offer boatbuilders a one-stop shop for all of their vessels' ventilation requirements, including engine room ventilation, HVAC, galley and head ventilation and unmanned space ventilation.
