ALPHA I5 CHEST IRONER
ALPHA I5 is a durable and reliable ironer with all the basic functions you need to achieve financial and operational goals. The ALPHA I5 utilizes JENSEN’s highly acclaimed top-quality flexible chest design. It is available in a steam model with highest level of evaporation capacity and a gas model with high energy efficiency and temperature control.

Flexible design, advantages of JENSEN’s highly acclaimed top-quality flexible chest design.
Flexible chest
The flexible chest consists of two layers of sheet metal welded together in a matrix pattern by a laser. This sandwich plate is rolled to the roll diameter and blasted with high pressure, thus forming small channels between the weldings. Gas chest is fully carbon steel, and steam chest uses a carbon steel inner plate welded to a stainless steel outer plate.
Optimal thermal conduction
Carbon steel in the flexible chest has a thermal conduction which is four times higher than that of e.g. stainless steel, maintaining a higher and more even temperature on the surface and thus a more efficient heat transfer to the linen.
Low friction
Carbon steel gives not only optimum thermal conduction, but also a low friction with wet linen, resulting in a nice finish. The low friction also reduces the wear of padding, ironing tapes and linen, as well as energy consumption.
Higher evaporation capacity
A traditional fixed chest loses contact as the padding wears out reducing the roll diameter, however a flexible chest adapts to the actual roll diameter. This maintains an optimal and stable contact angle, resulting in a higher evaporation capacity compared to that of a fixed chest.
Planetary gear
Planetary gear minimizes the counter torque and ensures that the roll will stay in its centered position during operation.
Exhaust control to reduce moisture in padding and prevent the roll from cooling down
The exhaust is ensured by a fan on each roll with a manually adjustable throttle valve which is connected to the main exhaust duct at the rear of the ironer.
Adjustable speed with adjustable V-belt pulleys
Adjustable v-belt pulleys make it possible to adjust the speed of each individual roll independently of each other,thus ensuring optimum finishing quality and longer lifetime of linen and padding.
Space saving solution
Due to the higher evaporation capacity, over time a flex chest 2 × 1200 ironer may equal that of a fixed chest 3 × 1200 ironer.
Energy Efficient self-contained gas heating concept ALPHA I5 gas heated model
Direct heating
The heat energy for ironing comes from a gas-fired burner enabling a laundry to lift off steam capacity for other purposes, and to run or expand its flatwork operation without heavy external piping and boiler room.
Reduced energy waste during start up and cool down
Due to the relatively low weight of the flexible chest, it can be heated in a fraction of the time and with a fraction of the energy required to heat a traditional chest.
Optimum flow
The heat energy is transferred to the ironer chest by a thermal fluid oil. An expansion tank is connected to the heat exchanger and the chest to absorb the heated oil as it expands.
Optimum heat transfer
Transfer of heat via the oil medium allows for high efficiency – up to 40% higher than that of steam. The key to an optimum transfer of heat from the oil into the chest is a high oil velocity and a turbulent flow combined with the higher thermal conduction of the carbon steel flexible chest of carbon steel.
