Harloff Premium Large Malignant Hyperthermia Cart (MH4300E-AC)

Malignant hyperthermia (MH) is a rare but life-threatening reaction to certain anesthesia drugs, and the American Association of Nurse Anesthetists (AANA) and Malignant Hyperthermia Association of the United States (MHAUS) both recommend keeping a dedicated, fully-stocked MH cart within immediate reach of every OR and PACU. The Harloff MH4300E-AC is built for exactly that: a three-drawer emergency cart with a built-in lab-quality refrigerator and an electronic pushbutton lock, so staff can retrieve Dantrolene, IV supplies, and refrigerated saline or insulin within seconds during an MH event.

The cart body is Harloff's 20-gauge powder-coated steel construction, sharing the same 51.5"H x 37.5"W x 26"D footprint used across Harloff's 3-drawer MH cart platform, on rolling casters with a removable plastic top. Three 3" storage drawers (23"W x 17"D usable interior) sit above a dedicated compartment housing the pre-installed refrigerator, giving staff organized, drawer-level access to charcoal filters, syringes, catheters, and other nursing and lab-testing supplies without digging through a single bin.

Cold storage is handled by a built-in Accucold 2.4 cu. ft. lab-quality refrigerator (model FF28LWHMED2) finished in white with a blue control panel. It uses fan-forced cooling for even top-to-bottom temperature control, non-CFC R134a refrigerant, epoxy-coated adjustable wire shelving, and a glycol-filled thermometer probe that meets CDC/VFC cold-chain documentation requirements, important for any facility storing regulated vaccines or medications alongside MH supplies.

Both the drawers and the refrigerator are secured by Harloff's electronic pushbutton lock: a membrane keypad supporting up to 20 user codes (19 staff plus 1 supervisor code), rated for roughly 75,000 open cycles before the externally-replaceable batteries need changing, and field-programmable so your team can manage access without sending the cart out for service. The cart ships standard with a waste container and mounting bracket, a large wire basket, and two chart/document holders, so it arrives ready to stock.

Harloff backs the MH4300E-AC with a 12-year limited warranty on its cabinets, drawers, and bumper frames, plus a 1-year warranty on purchased components like hardware, casters, and electronic locking parts. Mediplies ships every cart genuine, new, and fully insured to hospitals, surgery centers, and anesthesia departments nationwide.
