Jensen I5 Chest Ironer

JENSEN  I5 is a durable and reliable ironer with all the basic functions you need to achieve financial and operational goals. The JENSEN 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.

 

 

 

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.

 

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.

 

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.

 

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 minimizes the counter torque and ensures that the roll will stay in its centered position during operation.

 

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 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.

 

Due to the higher evaporation capacity, over time a flex chest 2 × 1200 ironer may equal that of a fixed chest 3 × 1200 ironer.

 

 

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.

 

Due to the higher evaporation capacity, over time a flex chest 2 × 1200 ironer may equal that of a fixed chest 3 × 1200 ironer.

 

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.

 

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.

 

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.

 

 

 

Uniform temperatures and highest possible evaporation capacity with the installed steam boiler capacity, which optimizes the heat transfer from steam to linen. The key to this optimum heat transfer is a turbulent steam flow combined with the carbon steel flexible chest. JENSEN has carried out extensive studies and tests on new methods of conducting the steam through the chest.

 

By using oil as the heating medium the JENSEN I5 Gas chest temperature can achieve temperatures of up to 230° C, 40° C higher than that of steam, when operating at a pressure of 12 bar.

 

The JENSEN I5 Gas model is designed to ensure a soft start and stop. A low flame is used at the start of production to prevent hot spots and superheating of oil until viscosity of oil decreases. Also the oil pump continues to run for a period after production stops, preventing superheating of the oil.

 

 

 

The JENSEN I5 serves as a distribution center for power and compressed air to the other equipment in the finishing lines, so the folder can easily be connected by the built-in plugs.

 

By using a flexible chest designed for the use of oil as the heating medium and an integrated gas-fired burner and heat exchanger, the JENSEN I5G minimizes the installation and set-up time, The JENSEN I5G is simply to be set in place and hooked up to a gas supply.

 

JENSEN stands for high quality, high value for money solution for customers who need dependable laundry machinery that can simply get the job done.

 

JENSEN is the world leading supplier of heavy-duty ironers, having delivered more than 2,500 ironers providing top-quality ironing and low-energy consumption to the industry. With a record sale of more than 10,000 folders and stackers to the laundry industry all over the world, JENSEN has the experience and knowhow to guarantee trouble-free finishing of all kinds of flatwork, ranging from high-capacity ironer lines for hospital linen to top-quality finishing of bed and table linen for high-end hotels and restaurants.

 

The JENSEN I5 is available as a stand-alone finishing unit with a delivery table for manual folding.

 

• Fast top-quality feeding
• 3 different types of feeding tables
• Standard width feeding table, 400 mm with separate toothed belt drive and with variable speed.
• Optional extended inclined inlet table, width 600 mm with shortened feeding height is ideal for smaller and larger linen offering ergonomic working conditions and excellent visual inspection of linen. It is especially suited for round table linen as it allows for careful guiding into ironer.
•  Optional built-in feeder JENSEN F5, incorporating a vacuum box which stretches the linen during the feeding process to ensure optimum feeding quality of large as well as small pieces.
