Binder FD-S 115 drying and heating oven, Solid.Line with forced air circulation, 106 l, up to 250 °C, 9090-0024

Larger batches of laboratory glassware, material samples or consumables require more internal space, but not necessarily sophisticated features. The Binder FD-S 115 is the larger model in the Solid.Line series: a forced-air drying and heating cabinet with a 106-litre usable volume, featuring the streamlined yet tried-and-tested specifications that BINDER has consistently limited to the essentials in the Solid.Line range. For laboratories and businesses seeking a reliable forced-air drying oven without the extensive additional functions of the Avantgarde.Line (FD series), this is a practical entry-level option offering noticeably more capacity than the smaller FD-S 56 model.

Solid.Line features: robust rather than overloaded

The temperature range extends from 10 °C above ambient temperature up to 250 °C. Control is handled by a controller with a timer function; the exhaust air flap is adjustable; and the air change rate at 100 °C is 2 air changes per hour. Even with this model, the APT.line preheating chamber technology ensures even temperature distribution inside the chamber, without the need for an LCD controller with advanced timing functions, such as those offered by the Avantgarde.Line models.

Heating behaviour and energy consumption

At 150 °C, the FD-S 115 achieves a spatial temperature deviation of 2.0 ± K and a temporal deviation of 0.4 ± K. The heating-up time to 150 °C is around 20 minutes; once the door is opened, the setpoint temperature is reached again after approximately 8 minutes. Energy consumption at 150 °C is 340 Wh/h, with a rated power of 1.3 kW (230 V) or 1.4 kW (120 V).

Typical applications

With a usable volume of 106 litres, the FD-S 115 is suitable for tasks where individual smaller drying cabinets reach their capacity limits, without the need for a large-scale unit.

• Drying larger quantities of laboratory glassware and sample containers
• Warm storage and conditioning of material batches
• Heat treatment of material samples in quality assurance
• Routine operation in industrial and training laboratories with higher throughput

With external dimensions of 764 x 616 x 735 mm and a weight of 48 kg, the FD-S 115 can still be easily accommodated on a sturdy laboratory bench or trolley.

Selection guide within the range

BINDER currently offers the Solid.Line FD-S series in two sizes, which are identical in terms of temperature range, control system and equipment, but differ significantly in terms of usable volume and footprint.

The FD-S 115 described here is the larger of the two models. If the 106-litre capacity is insufficient for your intended use, or if floor space is limited, it is worth considering the more compact FD-S 56 with a 55-litre capacity. Conversely, if you regularly need to dry larger batches of laboratory glassware or sample material in a single run, the FD-S 115 saves you from having to carry out additional drying cycles compared to the smaller model.

Distinction from the Avantgarde.Line, Classic.Line and natural convection

The Solid.Line is one of three equipment ranges in which BINDER offers drying and heating cabinets. It reliably covers the basic functions but does not include some of the features found in Avantgarde.Line models of the same volume, such as the FD 115: The temperature range tops out at 250 °C instead of 300 °C, and control is via a simpler controller with a timer function rather than an LCD display. In return, the Solid.Line has a lower entry-level price than the Avantgarde.Line.

For those who require gentler heat distribution without air movement inside the chamber, rather than forced air circulation, the Solid.Line range currently offers the ED-S 56 as a counterpart with natural convection. However, its usable volume of 62 litres is significantly lower than that of the FD-S 115; LT does not currently stock a larger Solid.Line model with natural convection. BINDER also uses the designation Classic.Line for certain smaller models. As the current master data does not provide a consistent record of which LT items belong to this third range, no specific classification is claimed here. An overview of the entire Binder range available from LT Laborhandel can be found in the ‘Climate Chambers & Incubators’ category.

Application, Operation and Maintenance

The heating-up time to 150 °C for the FD-S 115 is around 20 minutes; once the door is opened, the set temperature is reached again after approximately 8 minutes. The spatial temperature deviation of 2.0 ± K and the temporal deviation of 0.4 ± K at 150 °C are sufficient for most routine applications in drying and heat treatment. For larger batches that are reloaded more frequently, the recovery time of around 8 minutes has a direct impact on the total number of cycles possible per working day. The air change rate of 2 per hour at 100 °C is lower than that of the smaller FD-S 56, which must be taken into account when planning particularly moisture-sensitive drying processes.

Practical note: Standard, non-abrasive laboratory cleaners are suitable for cleaning the interior; abrasive or chlorine-based agents should be avoided. During unattended drying cycles, the integrated Class 2 temperature selector limiter in accordance with DIN 12880, featuring a visual alarm, provides additional protection against accidental overheating. Regular calibration ensures temperature accuracy over the course of the unit’s operational life; LT Laborhandel provides the relevant calibration certificates via its procurement service.

Investment rationale: When Solid.Line is sufficient, and when Avantgarde.Line is worthwhile

For routine tasks up to 250 °C, where a simple timer controller is sufficient, the Solid.Line reliably meets requirements at a lower cost than the Avantgarde.Line. If, on the other hand, a higher temperature range up to 300 °C is required, an LCD display with more precise process control is desired, or the process needs to be documented, a model such as the FD 115 from the Avantgarde.Line is the more suitable choice, even if this involves a higher purchase price. If, on the other hand, a smaller usable volume is sufficient, the more compact FD-S 56 also saves on floor space without compromising on temperature range or control.

The FD-S 115 comes as standard with a chrome-plated loading rack including a base support. For higher loading densities, additional loading racks are available as accessories, as are calibration certificates and maintenance contracts of varying scope, both available through LT Laborhandel’s procurement service.

What distinguishes the FD-S 115 from the FD-S 56?
The FD-S 56 offers 55 litres – roughly half the usable volume – with a significantly more compact footprint; otherwise, both models are technically identical in design.

What distinguishes the Solid.Line from the FD 115 model in the Avantgarde.Line?
The FD-S 115 covers a temperature range up to 250 °C, whilst the FD 115 covers a range up to 300 °C. The Avantgarde.Line is also controlled via an LCD display rather than a simple timer controller.

Is the FD-S 115 also available with a 120 V connection?
Yes, in addition to the 230 V version, the appliance is also available as a 120 V variant.

How do I clean the interior?
Standard, non-abrasive laboratory cleaners are suitable for cleaning; we advise against using abrasive or chlorine-based products (practical advice).
