Compare HTCR models by chamber volume and max temperature

Carbolite HTCR clean room ovens come in chamber volumes ranging from small 28 L units to large 1000 L models. Depending on the application, HTCR ovens are available with 400°C, 500°C, or 600°C max temperature options, making them suitable for drying, curing, and high-temperature clean-room processes.

HTCR ISO 14644-1 Class 5 versus Class 6 differences

HTCR ovens are designed for ISO Class 6 clean rooms as standard and can be configured for ISO Class 5 when tighter particle control is required. Class 5 environments allow significantly fewer particles than Class 6, so Class 5 HTCR units typically include enhanced sealing and additional clean-room protection features.

Installation and clean room penetration options for HTCR ovens

HTCR ovens support clean-room installation with features like sealed stainless-steel chambers, low-shedding insulation, and brushless fans. Optional clean-room penetration options include sealed feedthroughs, pass-through openings, validation ports, and custom service connections to maintain ISO clean-room integrity.

Typical lead time and warranty for Carbolite HTCR ovens

Standard HTCR models typically ship in 3–6 weeks, while customized Class 5 or option-heavy units may require 6–8+ weeks. Warranty terms generally range from 12 to 24 months, depending on region and distributor.

Accessories and optional controllers available for HTCR series

The HTCR series supports a range of accessories including perforated shelves, loading racks, viewing windows, validation ports, and HEPA filtration options. Controller upgrades include PID controllers, multi-segment programmable controllers, data-logging systems, alarms, and GMP-friendly validation packages.
